Indium nitride thin films are grown on sapphire substrates by metal-organic chemical vapour deposition (MOCVD) By employing three-step layer buffers, the mirror-like layers on two-inch sapphire wafers have been obta...
Superlattices with varying GaN well widths (2, 3, 6, 9 nm) and fixed AlGaN barrier (8 nm) with high Al-content (x=0.65) were grown. Streaky RHEED patterns indicated 2D growth mode for the superlattices. XRD measuremen...
A Si doped AlGaN/GaN HEMT structure with high Al content (x=43%) in the barrier layer is grown on sapphire substrate by RF-MBE.The structural and electrical properties of the heterostructure are investigated by the tr...
