Journal ArticleDOI
Disorder and the Optical-Absorption Edge of Hydrogenated Amorphous Silicon
TL;DR: The effect of thermal and structural disorder on the electronic structure of hydrogenated amorphous silicon is investigated by measurement of the shape of the optical absorption edge as a function of temperature and thermal evolution of hydrogen as discussed by the authors.
Journal ArticleDOI
Evidence for Exponential Band Tails in Amorphous Silicon Hydride
TL;DR: In this article, the conduction and valence-band width of amorphous silicon hydride is inferred from time-of-flight measurements of the temperature dependence of the electron and hole drift mobilities, and a multiple-trapping model of dispersive transport.
Journal ArticleDOI
Amorphous Semiconductor Superlattices
B. Abeles,Thomas Tiedje +1 more
TL;DR: In this article, the authors present mesures de diffraction RX, de photoconductivite, and of photoluminescence for superreseaux semiconducteurs.
Journal ArticleDOI
Optical characterization of amorphous silicon hydride films
TL;DR: In this paper, the optical properties of thin a-SiHx films were studied and the intrinsic optical limitations on the performance of the SiHx cells were defined for the absorption range 10−1-106 cm−1.
Journal ArticleDOI
Optical absorption above the optical gap of amorphous silicon hydride
TL;DR: In this article, the authors compared the Tauc model with the model first introduced by Tauc for optical transitions, with momentum conservation relaxed, between the valence (occupied) and conduction (unoccupied) bands of an amorphous semiconductor.
