Gallium Nitride Substrates|GaN Wafers

Fa'amatalaga Puupuu:

Gallium nitride (GaN), e pei o le silicon carbide (SiC), e aofia i le lona tolu o augatupulaga o mea semiconductor ma le lautele o le va o le lautele, ma le lautele o le va o le fusi, maualuga le vevela, maualuga le maualuga o le eletise, ma le maualuga o le eletise eletise mataʻina. uiga.GaN masini o loʻo i ai le tele o faʻamoemoega faʻaoga i le tele o taimi, saoasaoa maualuga ma le maualuga o manaʻoga manaʻoga e pei ole moli faʻaola le malosi o le LED, faʻaaliga faʻaalia leisa, taʻavale malosi fou, laina atamai, fesoʻotaʻiga 5G.

GaN Wafers

O le vaega lona tolu o mea semiconductor e masani ona aofia ai SiC, GaN, taimane, ma isi, aua o lona lautele gap lautele (Eg) e sili atu pe tutusa ma le 2.3 electron volts (eV), e lauiloa foi o mea lautele gap semiconductor mea. Pe a faatusatusa i mea semiconductor augatupulaga muamua ma lona lua, o le lona tolu o augatupulaga semiconductor mea e maua ai le tulaga lelei o le conductivity vevela maualuga, fanua malepe eletise maualuga, maualuga saturated electron fua faatatau femalagaiga ma le malosi fusia maualuga, lea e mafai ona ausia manaoga fou o tekinolosi faaonaponei mo le maualuga. vevela, malosi maualuga, maualuga maualuga, maualuga taimi ma faʻavevela tetee ma isi tulaga faigata. O loʻo i ai faʻamoemoega faʻaoga taua i vaega o le puipuiga a le atunuʻu, vaʻalele, aerospace, suʻesuʻega suauʻu, teuina o mata, ma isi, ma e mafai ona faʻaitiitia le malosi o le malosi e sili atu i le 50% i le tele o pisinisi faʻapitoa e pei o fesoʻotaʻiga lautele, malosi o le la, gaosiga o taavale, moli semiconductor, ma smart grid, ma e mafai ona faaitiitia le tele o meafaigaluega e sili atu i le 75%, lea e taua tele mo le atinaeina o le faasaienisi ma tekinolosi tagata.
