Properties of p-GaN Layer on Different Nitride Surfaces
Achieving high-quality p-type GaN (p-GaN) layer is crucial for development of nitrides-based optoelectronic and power devices like as light-emitting diodes (LEOs). laser, transistor and so forth. Although, nitride based devices are commonly grown on foreign substrates e.g. sapphire, growing the n...

| description | Achieving high-quality p-type GaN (p-GaN) layer is crucial for development of nitrides-based
optoelectronic and power devices like as light-emitting diodes (LEOs). laser, transistor and so forth.
Although, nitride based devices are commonly grown on foreign substrates e.g. sapphire, growing the
nitrides based devices in cheap substrate like silicon (Si) is more preferable as it can promote the
devices production at low-cost level. Apart from that, Si substrate provides good thermal conductivity,
easier fabrication and available in larger wafer size. It should be concerned that, the nitrides grown on
Si substrate usually suffer from large lattice mismatch that causes crack and defects in the overgrown
GaN layer. To overcome the problem, we propose to use aluminum nitride (AIN) as the buffer layer for
p-GaN layer. In this work, we investigate the structural, optical and electrical properties of p-GaN layer
grown on different nitrides surfaces using Si and sapphire substrates for comparison. Towards the
end, the prospective of the p-GaN layer on AIN/Si substrate will be determined. |
