    Direct-current generation due to wave mixing in semiconductors
/ K. N. Alekseev, M. V. Erementchouk, F. V. Kusmartsev // Europhys. Lett. - 1999. - Vol. 47, Is. 5. - P. 595-600, DOI 10.1209/epl/i1999-00430-0. - Cited References: 34 . - ISSN 0295-5075

Аннотация: We describe an effect of the generation of direct current which may arise in semiconductors or semiconductor microstructures due to a mixing of coherent electromagnetic radiations of commensurate frequencies. The effect is, in essence, due to a nonparabolicity of the electron energy bands and is stronger in systems where this nonparabolicity is greater. We have made exact calculations in the framework of the Kane model, applicable to narrow-gap semiconductors and the tight-binding model which we employ for a description of a semiconductor superlattice.

    Broadband Tamm plasmons in chirped photonic crystals for light-induced water splitting
/ M. V. Pyatnov, R. G. Bikbaev, I. V. Timofeev [et al.] // Nanomaterials. - 2022. - Vol. 12, Is. 6. - Ст. 928, DOI 10.3390/nano12060928. - Cited References: 41 . - ISSN 2079-4991

Аннотация: An electrode of a light-induced cell for water splitting based on a broadband Tamm plasmon polariton localized at the interface between a thin TiN layer and a chirped photonic crystal has been developed. To facilitate the injection of hot electrons from the metal layer by decreasing the Schottky barrier, a thin n-Si film is embedded between the metal layer and multilayer mirror. The chipping of a multilayer mirror provides a large band gap and, as a result, leads to an increase in the integral absorption from 52 to 60 percent in the wavelength range from 700 to 1400 nm. It was shown that the photoresponsivity of the device is 32.1 mA/W, and solar to hydrogen efficiency is 3.95%.
