Raman scattering in resonance with yellow luminescence transitions in GaN layers grown on sapphire by molecular beam epitaxy

Tripathy, S; Soni, R K; Asahi, H; Gonda, S (2000)

We have carried out defect-induced Raman scattering in resonance with yellow-luminescence (YL) transitions in GaN layers grown on sapphire by electron cyclotron resonance-molecular beam epitaxy technique. The photoluminescence ...

Optical transitions and interface structure in (GaP)m/(AlP)n modulated period superlattices

Soni, R K; Tripathy, S; Asahi, H (2004)

We have investigated optical transitions and atomically controlled interface structure in modulated period (GaP)m/(AlP)n (m, n number of monolayers) superlattices (SLs) using low-temperature photoluminescence (PL) and Raman ...
