Computer modelling and experimental characterisation of amorphous semiconductor thin films and devices
Computer source codes for modelling amorphous semiconductors have been developed during the course of the study. The major program <i>SPIN.F</i> deals with steady state electronic processes for amorphous semiconductor materials and devices under different optical excitation and applied voltage …

Optical Transitions in Amorphous Semiconductors
… analysis of the optical response of an amorphous semiconductor is presented. The entire analysis is cast within the framework of an empirical model for the valence band and conduction band density of states functions, that captures the basic features expected of these functions. A novel …

A STUDY OF SWITCHING PHENOMENA IN DISCONTINUOUS AU AND TI FILMS
… Presently, researchers are concentrating on the amorphous semiconductors. However, switching properties have been reported in discontinuous thin metal films, and this thesis reports on results for discontinuous gold and discontinuous titanium. Due to apparent similarities in the operation of …

Polymer-derived Ceramics: Electronic Properties And Application
… that the SiCN ceramics exhibited typical amorphous semiconductor behavior, and their conductivity varied in a large range. The results also revealed that the materials contain more than one phase, which have the different electronic behavior. We explored possibility of using …

First principles-based atomistic modeling of the structural properties of silicon-oxide nanomaterials
… of predicting the structural properties of amorphous semiconductor and oxide materials as well as their interface. To bolster the reliability of the CRN model, we have developed force fields based on gradient corrected density functional theory (DFT) calculations. Our in-house CRN-MMC tools …

Transient photoconduction in amorphous materials
… current pulses that would be expected for amorphous materials possessing known density of states distributions. Two simulation methods are used, the Monte Carlo technique and the finite difference method. While the Monte Carlo method makes few basic assumptions, the transients produced are …

Carrier mobility of downscaled amorphous semiconductors exemplified by hydrogenated amorphous silicon
… Internet of Things (IoT) facilities. Amorphous semiconductors are among the most favoured channel semiconductors in TFTs because of their irreplaceable merits such as large-area uniformity, low cost and low thermal budget which are essential to the above use cases. Nevertheless, the …
