Threshold switches based on amorphous semiconductors possess a number of attractive features if they are easily fabricable and do not deteriorate with time. Extensive review of the literature and theoretical considerations suggest that such switches can be conveniently fabricated and that some materials can be stable even after long periods of usage. Preliminary experimental work was undertaken to evaluate the most promising materials and fabrication method. Oxide glasses based on V2O5 and P2O5 were prepared and compounded into the form of ink. Thick film technique was used to prepare switches. A power supply system was then designed and fabricated incorporating amorphous semiconductor switches. Results indicated that such switches have long-term stability and can show satisfactory performance in power supply systems.
