Doped Amorphous Semiconductors

Defects in Amorphous Semiconductors: Amorphous Silicon

Defects in disordered (amorphous) semiconductors are discussed, with an emphasis on hydrogenated amorphous silicon. The general differences between defect phenomena in crystalline and amorphous hosts are described, and the special importance of the electron–phonon coupling is stressed. Detailed calculations for amorphous Si are presented using accurate first principles (density-functional) tech...

Doped Semiconductors: Role of Disorder

Charge-carrier transport in amorphous organic semiconductors

Organic semiconductors have been extensively studied ever since the successful fabrication of organic light-emitting diodes (OLED).4 2-44 Due to their success, it is becoming increasingly important to understand the theory behind the properties of organic materials. In order to exploit all the advantages of implementing organic materials to construct devices, a detailed understanding of charge-...

Nuclear Quadrupole Resonance in Amorphous Semiconductors *

Nuclear quadrupole resonance ( N Q R ) has provided a valuable tool for investigating the local structural order in semiconducting glasses. Measurements of N Q R lineshapes and spin-lattice relaxation times help elucidate the local structural order and the unusual vibrational properties, respectively, o f these glasses. In addition, N Q R lineshape measurements on samples that are made under co...
