Ukukhula kweekristale zesemiconductor edibeneyo
I-Compound semiconductor yaziwa ngokuba sisizukulwana sesibini sezixhobo ze-semiconductor, xa kuthelekiswa nesizukulwana sokuqala semathiriyeli ye-semiconductor, ene-optical transition, i-high electron saturation drift rate kunye nokumelana nobushushu obuphezulu, ukumelana nemitha kunye nezinye iimpawu, kwi-ultra-high speed, i-ultra-high. i-frequency, amandla aphantsi, ingxolo ephantsi yamawaka kunye neesekethe, ngokukodwa izixhobo ze-optoelectronic kunye nokugcinwa kwe-photoelectric kuneenzuzo ezikhethekileyo, olona mmeli walo li-GaAs kunye ne-InP.
Ukukhula kweekristale ezidibeneyo ze-semiconductor enye (ezifana nee-GaAs, i-InP, njl.) kufuna iimeko ezingqongqo ngokugqithisileyo, kubandakanywa ubushushu, ukucoceka kwempahla eluhlaza kunye nokucoceka kweenqanawa zokukhula.I-PBN okwangoku iyinqanawa efanelekileyo yokukhula kweekristale ze-semiconductor enye.Okwangoku, i-compound semiconductor enye yekristale iindlela zokukhula ikakhulu zibandakanya ulwelo lwetywina lokutsala ngokuthe ngqo (LEC) kunye nendlela yokuqinisa i-gradient ethe nkqo (VGF), ehambelana neBoyu VGF kunye neemveliso ze-LEC ze-crucible series.
Kwinkqubo ye-polycrystalline synthesis, i-container esetyenziselwa ukubamba i-elemental gallium kufuneka ikhululeke kwi-deformation kunye nokuqhekeka kwiqondo lokushisa eliphezulu, ifuna ukucoceka okuphezulu kwesikhongozeli, kungabikho ukwaziswa kokungcola, kunye nobomi benkonzo ende.I-PBN inokuhlangabezana nazo zonke ezi mfuno zingentla kwaye iyisitya esifanelekileyo sokusabela kwi-polycrystalline synthesis.Boyu PBN isikhephe series iye yasetyenziswa ngokubanzi kule teknoloji.
