Excess Modes and Enhanced Scattering in Rare-Earth Doped Amorphous Silicon Thin Films

B. L. Zink, R. Islam, David J. Smith +1

We report specific heat and thermal conductivity of gadolinium- and yttrium-doped amorphous silicon thin films measured using silicon-nitride membrane-based microcalorimeters. Addi…

Charge dynamics and metal-insulator transition in Si $_{1 - x}$ Gd $_{x}$ and Si $_{1 - x}$ Y $_{x}$ alloys

D. N. Basov, A. M. Bratkovsky, P. F. Henning +5

Carrier dynamics in amorphous a-Si $_{1 - x}$ RE $_{x}$ (RE=Gd, Y) films has been studied in the doping regime close to the metal-insulator transition by means of infrared spectroscopy.…
