| Research Abstract |
Vapor phase epitaxy (VPE) including metalorganic vapor phase epitaxy (MOVPE) is a very important method for high-functional opto- and electronic- devices. VPE provides high quality epitaxial layers from vapor at low temperature. Group III nitrides and their alloys are promising materials for applications to short-wavelength light emitting devices. In particular, fabrication of InGaN-based heterostructures has been extensively studied for violet/blue laser diodes (LDs) by a large number of researchers. Especially, MOVPE is used generally for the epitaxial growth of these structures.
In this project, we have investigated a new thermodynamic analysis system for vapor phase epitaxy of the group III nitrides, GaN, InN, AIN, InGaN, AlGaN and AlInN, and the other III-V compound semiconductors such as InGaAsP, InAsAs, InGaP because the thermodynamic analysis of epitaxial growth system provides usefull information on the growth conditions. The new thermodynamic analysis system which we set up informs 〓vorable conditions for the growth through the internet web to any researchers who want to find out the best conditions.
