Pyrolytic Boron Nitride Alaabta PBN
Dulmarka alaabta
Pyrolytic Boron Nitride (PBN) waxaa sameeyay habka loo yaqaan 'Chemical Vapor Deposition' (CVD) kaas oo gaaska ammonia (NH3) iyo gaaska boron halide sida boron trichloride (BCI3) ay uga falceliyaan foornada CVD heerkulkeedu sarreeyo si loo dhigo. PBN on substrate ku habboon sida Pyrolytic Graphite.
PBN waxaa loo yaqaanaa doorasho aad u fiican oo loogu talagalay foornada heerkulka sare leh iyo qaybaha korantada, semiconductor, iyo kiristaalo ka samaysan microwave sida germanium (Ge), gallium arsenide (GaAs), iyo indium phosphate (InP) taas oo ay ugu wacan tahay nadiifnimadeeda gudaha, sifooyinka farsamada sare , iyo xasilloonida physicochemical. PBN waxay u adkeysan kartaa 1800°C faakuumka iyo 2000°C ee nitrogen, taasoo u soo bandhigaysa door wanaagsan oo loogu talagalay qaybaha foornada iyo weelasha dhalaalinta.
