Yini i-GaN futhi kungani uyidinga?

I-Gallium nitride, noma i-GaN, iwumsebenzi oqala ukusetshenziselwa ama-semiconductors kumashaja. Yayisetshenziselwa ukwenza ama-LED kusukela ngeminyaka yawo-'90s, futhi iyinto edumile yamaseli elanga kumasathelayithi. Okubalulekile nge-GaN uma kukhulunywa ngamashaja ukuthi ikhiqiza ukushisa okuncane. Ukushisa okuncane kusho ukuthi izingxenye zingasondelana ndawonye, ​​ngakho ishaja ingaba yincane kunangaphambilini—kube igcina wonke amandla namazinga okuphepha.

Yenzani ngempela ishaja?

Siyajabula ukuthi ubuze.

Ngaphambi kokuthi sibheke i-GaN ngaphakathi kweshaja, ake sibheke ukuthi ishaja yenzani. Ngamunye wethu omakhalekhukhwini, amathebulethi, namakhompyutha aphathekayo anebhethri. Uma ibhethri lidlulisela amandla kumadivayisi ethu, okwenzekayo empeleni ukusabela kwamakhemikhali. Ishaja ithatha amandla kagesi ukuze ihlehlise lokho kusabela kwamakhemikhali. Ezinsukwini zakuqala, amashaja ayevele athumele ijusi ebhethrini njalo, okungaholela ekushajweni ngokweqile kanye nomonakalo. Amashaja esimanje ahlanganisa amasistimu okuqapha anciphisa amandla ombane njengoba ibhethri ligcwala, okunciphisa amathuba okushajwa ngokweqile.

Ukushisa kuvuliwe:
I-GaN ithatha indawo ye-silicon

Kusukela ngawo-'80s, i-silicon ibilokhu iyinto ehamba phambili yama-transistors. I-Silicon iqhuba ugesi kangcono kunezinto ezisetshenziswe ngaphambilini—njengamashubhu e-vacuum—futhi igcina izindleko ziphansi, njengoba kungabizi kakhulu ukuyikhiqiza. Emashumini eminyaka adlule, ukuthuthukiswa kobuchwepheshe kuholele ekusebenzeni okuphezulu esikujwayele namuhla. Ukuthuthuka kungahamba kuze kube manje, futhi ama-silicon transistors angase asondele kokuhle njengoba azothola. Izakhiwo ze-silicon material ngokwazo ngokufika kokushisa nokudluliswa kukagesi kusho ukuthi izingxenye azikwazi ukuba zincane.

I-GaN ihlukile. Kuyinto efana nekristalu ekwazi ukwenza ama-voltage aphezulu kakhulu. Amandla kagesi angadlula ezingxenyeni ezenziwe nge-GaN ngokushesha kune-silicon, okuholela ekucutshungulweni ngokushesha okukhulu. I-GaN isebenza kahle kakhulu, ngakho-ke kunokushisa okuncane.
