Rezumat | ||||||
A technique for fabricating n-GaN/Si heterojunctions, which includes chemical deposition of GaN layers with thicknesses of up to 20 μm on a Si substrate in an open gas-transport system, is developed. The photoelectric properties of isotypic and anisotypic heterojunctions are studied in natural and linearly polarized light. A polarization photosensitivity is observed when linearly polarized light is obliquely incident on the surface of the GaN layers. The induced photopleochroism increases quadratically with the angle of incidence θ and reaches 20% for θ≅75°. GaN/Si heterojunctions may be useable as broad-band photoanalyzers of linearly polarized light. |
