Walxaha Kululaynta ee MOCVD Substrate

Walxaha kuleylinta ee MOCVD Substrate Sawirka

Sharaxaad Gaaban:

Walxaha Kululaynta Semicera ee Substrate-ka MOCVD waxa loo habeeyey si ay u bixiyaan xakamaynta heerkulka saxda ah oo degan hababka Kaydinta Kiimikada ee Birta-Organic (MOCVD). Waxaa laga sameeyay garaafka tayada sare leh, walxahan kuleyliyaha ah waxay bixiyaan kuleyl heer sare ah, kuleyl isku mid ah, iyo isku haleyn waqti dheer ah. Ku habboon wax-soo-saarka semiconductor, wax-soo-saarka LED-ka, iyo codsiyada agabka horumarsan, walxaha kuleylka Semicera waxay xaqiijiyaan waxqabad joogto ah, iyagoo sare u qaadaya habka substrate-kaaga MOCVD waxtarka iyo tayada ugu sarreeya.

Tilmaamaha ugu muhiimsan ee kuleyliyaha garaafka:

1. isku mid ahaanshaha qaab dhismeedka kuleylka.

2. koronto wanaagsan iyo culeys koronto oo sarreeya.

3. iska caabin daxalka.

4. oksidizability.

5. nadiifinta kiimikada sare.

6. xoogga farsamada sare.

Faa'iidada waa tamar hufan, qiimo sare iyo dayactir hooseeya. Waxaan soo saari karnaa ka-hortagga oksaydhka iyo cimriga dheer ee garaafiga crucible, caaryada garaafka iyo dhammaan qaybaha kuleyliyaha garaafka.
