The steady-state photocarrier grating technique allows the determination of the ambipolar
diffusion length in low-mobility semiconductors and provides access to the minority-carrier …

We have measured the subgap optical absorption of undoped microcrystalline silicon
samples with photothermal deflection spectroscopy and compared it with the spin density …

Metastable changes in the dark conductivity of microcrystalline silicon upon heat treatment
at different temperatures obey the Meyer–Neldel rule. Dark conductivity variations are …

This chapter gives an account of the Steady‐State Photocarrier Grating (SSPG) method with
some emphasis on the setup, on the necessary and complementary measurement steps …

We demonstrate that metastable changes or instabilities in the dark conductivity of
microcrystalline silicon upon heat treatment and ambient conditions, which have been …
