摘要： A highly sensitive thermally stimulated emission (TSE) spectrometer, and a method of conducting spectrometry, are described. Provided is a thermally stimulated emission (TSE) spectrometer comprising a cryostat housing a sample stage in an area; a cooling source configured to lower a temperature of the area to as low as 9 K; a photo-excitation source configured to deliver electromagnetic radiation to a sample on the sample stage; a heat source configured to heat the area; a temperature control unit configured to control the cooling source and the heat source, so as to cool or heat the area; a monochromator configured to receive light emitted from the sample on the sample stage as the area is being heated by the heat source, and emit a specific wavelength or wavelengths of the light; a highly sensitive photomultiplier tube (PMT) configured to detect the light emitted from the monochromator at the specific wavelength or the light emitted directly from the sample covering all wavelengths.

摘要： A method for bipolar doping of oxide semiconductor materials, a method for doping an oxide semiconductor material n-type, a method for doping an oxide semiconductor material p-type, and products of the same are described. Also described is p-type Ga2O3 having hydrogen atoms as dopants. Also described is n-type Ga2O3 having hydrogen atoms as dopants, or having both of a sheet carrier concentration of at least about 1016 cm2, and/or a mobility of at least about 100 cm2/VS at room temperature.
