Diamond-like carbon (DLC) is a metastable form of amorphous carbon with significant sp3
bonding. DLC is a semiconductor with a high mechanical hardness, chemical inertness, and …

The need to develop inexpensive renewable energy sources stimulates scientific research
for efficient, low-cost photovoltaic devices. 1 The organic, polymer-based photovoltaic …

Luminescence and related investigations of recombination in hydrogenated amorphous
silicon prepared by glow discharge and sputtering are described. Emphasis is given to a …

It is known that in disordered semiconductors with purely exponential energy distribution of
localized band-tail states, as in amorphous semiconductors, all transport phenomena at low …

The Efros–Shklovskii (ES) Coulomb gap in the one-electron density of localized states and
the ES law of the variable range hop** conductivity were coined 50 years ago. The theory …

Charge carrier recombination in organic disordered semiconductors is strongly influenced
by the thermalization of charge carriers in the density of states (DOS). Measurements of …

A study of donor electron spins and spin-dependent electronic transitions involving
phosphorous (P 31) atoms in proximity to the (111) oriented crystalline silicon (c-Si) to …

A particular energy level in the band tail of a disordered semiconductor, called the 'transport
energy', plays a crucial role in hop** transport of carriers in both equilibrium and non …

Using undoped hydrogenated amorphous silicon (a-Si: H) containing ND= 6.7× 1015cm-3
native dangling bond (DB) defects we found that metastable DB defects can be created with …

This chapter surveys general theoretical concepts developed to qualitatively understand and
to quantitatively describe the electrical conduction properties of disordered organic and …
