ABSTRACT:
The present invention is directed to electronic devices comprising high-purity molybdenum oxide in at least a part of the devices. The devices according to the present such a bipolar transistor, a field effect transistor and a thyristor have a high withstand voltage. The present invention is directed also hostile-environment electron devices formed using high-purity molybdenum oxide. The devices according the present invention can be fabricated at a relatively lower temperature such as 700° C. than that at which GaN or SiC devices are fabricated, the at is a temperature higher than 1000° C.
