Research Abstract |
AlGaN semiconductor is one of the promising widest band-gap semiconductor, by which UV and deep-UV light emitting devices and also high power electronics devices could be achieved. However, the semiconductor has several difficult problems to be solved, such as (1)How we achieve the high quality AlGaN, (2)How we achieve high carrier density and low resistivity p-type AlGaN for device applications. In this study, we have proposed the "Alternate Source-Feeding Epitaxial technique" by which extremely high quality AlGanN will be achieved. And, We have achieved high carrier density p-type AlGaN with up to 55% of Al solid composition using "Carbon" as an acceptor in the AlGaN, then we have also demonstrated the first p-n junction using the carbon-doped p-type AlGaN.
