Silicon-on-insulator -- Schottky contacts FET -- Si nanowire biosensor -- Back gate nanowire FET
Аннотация: A top-down nanofabrication approach involving molecular beam epitaxy and electron beam lithography was used to obtain silicon nanowire-based back gate field-effect transistors with Schottky contacts on silicon-on-insulator (SOI) wafers. The resulting device is applied in biomolecular detection based on the changes in the drain-source current (IDS). In this context, we have explained the physical mechanisms of charge carrier transport in the nanowire using energy band diagrams and numerical 2D simulations in TCAD. The results of the experiment and numerical modeling matched well and may be used to develop novel types of nanowire-based biosensors.

Аннотация: The atomic structure and elastic properties of silicon carbide nanowires of different shapes and effective sizes were studied using density functional theory and classical molecular mechanics. Upon surface relaxation, surface reconstruction led to the splitting of the wire geometry, forming both hexagonal (surface) and cubic phases (bulk). The behavior of the pristine SiC wires under compression and stretching was studied and Young's moduli were obtained. For Y-shaped SiC nanowires the effective Young's moduli and behavior in inelastic regime were elucidated.

   Перевод заглавия: Micromagnetic modelling of the polycrystaline structure effect to the ysteresis loop in ferromagnetic nanowire
Кл.слова (ненормированные):
нанонит -- коэрцитивность -- микромагнетизм
Аннотация: Проведено систематическое микромагнитное моделирование петель гистерезиса ферромагнитных нанонитей представляющих собой одномерную цепочку случайно ориентированных кристаллитов и учитывающее три основных вклада в магнитную энергию нити (обменный, диполь-дипольный и энергию анизотропии кристаллита). В случаях, когда одним из трех вкладов в энергию можно пренебречь, численные расчеты хорошо согласуются с результатами известных, аналитически изученных микромагнитных проблем. В случае, когда все три вклада сопоставимы, наблюдается сложное немонотонное поведение коэрцитивной силы от размера кристаллита и константы магнитной анизотропии. С целью интерпретации этих изменений вводится новый микромагнитный масштаб, учитывающий все три вклада в магнитную энергию нити, а также осуществляющий корректный переход к аналитически изученным пределам, учитывающим конкуренцию каких-либо двух вкладов.
Extensive micromagnetic simulation results of the hysteresis loops in ferromagnetic nanowire with randomly oriented crystallites ordered in one chain is presented. Three main contributions to the magnetic energy of the wire had been taken into account: exchange, dipole-dipole, and the magnetic anisotropy energy of the crystallite. In cases where one of the three contributions to the energy can be neglected, the numerical calculations are in good agreement with the results of the well-known, analytically studied micromagnetic problems. In the case when all three contributions are comparable, a complex non-monotonic dependence of the coercive force on the crystallite size and the magnetic anisotropy constant is observed. In order to interpret these changes, a new micromagnetic scale is introduced, which takes into account all three contributions to the magnetic energy of the wire, and performs a correct transition to the analytically studied limits, which take into account the competition of any two contributions.

silicon on insulator -- transistor -- Schottky barrier -- electron lithography -- nanowire -- reactive ion etching -- electron transport
Аннотация: Semiconductor nanowires are unique materials for studying nanoscale phenomena; the possibility of forming silicon nanowires on bulk silicon-on-insulator substrates in a top-down process ensures complete incorporation of this technology into integrated electronic systems. In addition, the use of ferromagnetic contacts in combination with the high quality of ferromagnetic–semiconductor interfaces open up prospects for the use of such structures in spintronics devices, in particular, spin transistors. A simple approach is proposed to create semiconductor nanowire-based active devices, specifically, bottom-gate Schottky-barrier field-effect transistors with a metal (Fe) source and drain synthesized on a silicon-on-insulator substrate and the transport characteristics of the designed transistors are investigated.

Аннотация: The atomic structure and elastic properties of Y-shaped silicon nanowires of "fork"- and "bough"-types were theoretically studied, and effective Young moduli were calculated using Tersoff interatomic potential. The oscillation of fork Y-type branched nanowires with various branch lengths and diameters was studied. In the final stages of the bending, the formation of new bonds between different parts of the wires was observed. It was found that the stiffness of the nanowires is comparable with the stiffness of Y-shaped carbon nanotubes.

Аннотация: The fermion parity of the ground state is determined in various topological phases of the semiconducting nanowire under external magnetic field with proximity-induced superconductivity and strong spin-orbit interaction. Electron hopping as well as spin-flip hopping due to spin-orbit coupling and superconducting pairings in the second coordination sphere are taken into account. The connection between the fermion parity and the parity of the BDI topological invariant is shown. The formation of topological phases with three and four pairs of Majorana modes has been demonstrated.
Для полупроводниковой нанопроволоки, помещенной во внешнее магнитное поле, с наведенной сверхпроводимостью и сильным спин-орбитальным взаимодействием определена фермионная четность основного состояния в различных топологических фазах при учете перескоков электронов, включая перескоки с переворотом спина за счет спин-орбитальной связи, и сверхпроводящих спариваний во второй координационной сфере. Показана связь фермионной четности и четности BDI топологического инварианта. Продемонстрировано формирование топологических фаз с тремя и четырьмя парами майорановских мод.

superconducting nanowires -- Majorana zero modes -- strong electron correlations
Аннотация: For superconducting nanowire with the pairing of extended s-type symmetry, Rashba spin-orbit interaction in a magnetic field, the influence of strong intersite charge correlations on single-particle Majorana excitations is analyzed. This problem is investigated on the basis of the density matrix renormalization group numerical method. It is shown that with an increase in the repulsion intensity of electrons located at the neighboring sites, two subbands emerge in the lower Hubbard band of the open system. Based on calculations of the Majorana polarization and degeneracy of the entanglement spectrum, it was found that a topologically nontrivial phase with one edge state survives at the edge of each of the subbands where the concentration of electrons or holes is minimal.

Аннотация: The quantum confinement effect (QCE) of linear junctions of silicon icosahedral quantum dots (IQD) and pentagonal nanowires (PNW) was studied using DFT and semiempirical AM1 methods. The formation of complex IQD/PNW structures leads to the localization of the HOMO and LUMO on different parts of the system and to a pronounced blue shift of the band gap; the typical QCE with a monotonic decrease of the band gap upon the system size breaks down. A simple one-electron one-dimensional Schrodinger equation model is proposed for the description and explanation of the unconventional quantum confinement behavior of silicon IQD/PNW systems. On the basis of the theoretical models, the experimentally discovered deviations from the typical QCE for nanocrystalline silicon are explained.
