Description
The electronics industry is fundamental nowadays and semiconductors play a determining role. The most widely used is, by far, silicon (Si). However, it is not the only one, and many other semiconductors with different properties are explored for specific applications. For example, due to its wide bandgap, gallium oxide (Ga2O3) has aroused interest for optoelectronic applications, such as solar blind UV photodetectors, and power electronic devices. Recently, a new method for exfoliation of Ga2O3 membranes was found, in which a crystal is implanted with ions, causing surface layers to roll into tubes. In this project, the potential of these membranes for application in nanodevices, such as transistors and UV detectors, will be demonstrated. To achieve this goal will require: the improvement of the tube transfer process to new substrates and its unrolling to obtain a membrane; the optimisation of the electrical contacts, Ohmic and Schottky, to these membranes; and, finally, the characterisation of the resulting devices.
