Ukukhula kwamakristalu ahlanganisiwe we-semiconductor
I-Compound semiconductor yaziwa njengesizukulwane sesibili sezinto zokwakha ze-semiconductor, uma iqhathaniswa nesizukulwane sokuqala sezinto zokwakha ze-semiconductor, ne-optical transition, high electron saturation drift rate kanye nokumelana nokushisa okuphezulu, ukumelana nemisebe nezinye izici, ngesivinini esiphezulu, i-ultra-high. imvamisa, amandla aphansi, izinkulungwane zomsindo ophansi namasekhethi, ikakhulukazi amadivayisi we-optoelectronic kanye nesitoreji se-photoelectric kunezinzuzo eziyingqayizivele, okumelela kakhulu okuyi-GaAs ne-InP.
Ukukhula kwekristalu eyodwa ye-semiconductor ehlanganisiwe (njengama-GaAs, i-InP, njll.) kudinga izindawo eziqine kakhulu, okuhlanganisa izinga lokushisa, ukuhlanzeka kwempahla eluhlaza kanye nokuhlanzeka komkhumbi wokukhula.I-PBN njengamanje ingumkhumbi okahle wokukhula kwekristalu eyodwa ye-semiconductor eyodwa.Njengamanje, izindlela zokukhula kwe-crystal semiconductor eyodwa ikakhulukazi zifaka indlela yokudonsa eqondile ye-liquid seal (LEC) kanye nendlela yokuqinisa i-gradient solidification (VGF), ehambisana ne-Boyu VGF kanye nemikhiqizo ye-LEC yochungechunge lwe-crucible.
Enqubweni yokwenziwa kwe-polycrystalline synthesis, isitsha esisetshenziselwa ukubamba i-elemental gallium sidinga ukungabi nakuguqulwa nokuqhekeka ezingeni lokushisa eliphezulu, esidinga ukuhlanzeka okuphezulu kwesiqukathi, ukwethulwa kokungcola, nempilo ende yesevisi.I-PBN ingahlangabezana nazo zonke lezi zidingo ezingenhla futhi iyisitsha esihle sokusabela se-polycrystalline synthesis.Uchungechunge lwesikebhe lwe-Boyu PBN lusetshenziswe kabanzi kulobu buchwepheshe.
