Nkọwa Dị Mkpirikpi:

Ihe mkpuchi epitaxial InP bụ ihe ndabere maka imepụta APD, nke na-abụkarị ihe semiconductor nke e tinyere na substrate site na teknụzụ uto epitaxial. Ihe ndị a na-ejikarị eme ihe gụnyere silicon (Si), gallium arsenide (GaAs), gallium nitride (GaN), wdg, nwere ezigbo ihe fotoelectric. Ihe nchọpụta foto APD bụ ụdị fotodetector pụrụ iche nke na-eji mmetụta fotodetector avalanche eme ka akara nchọpụta dịkwuo mma. Mgbe foton mere na APD, a na-emepụta ụzọ abụọ electron-hole. Ọsọ nke ndị na-ebu ibu ndị a n'okpuru ọrụ nke ubi eletrik nwere ike ibute ịmepụta ọtụtụ ndị na-ebu ibu, "mmetụta nnukwu mmiri", nke na-eme ka ọkụ mmepụta dịkwuo elu.
A na-eji akwa mmiri Epitaxial nke MOCvD kụrụ bụ isi ihe dị na ngwa nchọpụta foto nke oke mmiri. Ihe U-InGaAs mere ya na ihe eji etinye ihe n'azụ <5E14. A na-eji InP ma ọ bụ InAlAslayer emepụta akwa mmiri Epitaxial. InP epitaxial substrate bụ ihe bụ isi maka imepụta APD, nke na-ekpebi arụmọrụ nke ihe nchọpụta anya. APD photodetector bụ ụdị ihe nchọpụta foto dị elu, nke a na-ejikarị eme ihe n'ọhịa nkwukọrịta, nchọpụta na onyonyo.
