Mawonekedwe

●Chingwe Chokulirapo:GaN (3.4 eV) imapereka kusintha kwakukulu pakugwira ntchito kwa ma frequency apamwamba, mphamvu zapamwamba, komanso kutentha kwambiri poyerekeza ndi silicon yachikhalidwe, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsa ntchito zida zamagetsi ndi ma amplifier a RF.
●Kusintha Koyenera kwa Si Substrate:Sankhani kuchokera ku njira zosiyanasiyana za Si monga <111>, <100>, ndi zina kuti zigwirizane ndi zofunikira pa chipangizocho.
● Kusasinthika Kwapadera:Sankhani pakati pa njira zosiyanasiyana zotetezera mphamvu ya Si, kuyambira pa kutetezera mphamvu pang'ono mpaka kukana mphamvu kwambiri komanso kukana mphamvu pang'ono kuti muwongolere magwiridwe antchito a chipangizocho.
● Mtundu wa mankhwala osokoneza bongo:Imapezeka mu mtundu wa N kapena P-type doping kuti igwirizane ndi zofunikira za zida zamagetsi, ma RF transistors, kapena ma LED.
●Kuwonongeka Kwambiri kwa Mphamvu yamagetsi:Ma wafer a GaN-on-Si ali ndi mphamvu yamagetsi yotsika kwambiri (mpaka 1200V), zomwe zimawalola kuti agwire ntchito pogwiritsa ntchito mphamvu yamagetsi yokwera kwambiri.
●Kuthamanga Kofulumira Kwambiri:GaN ili ndi kuyenda kwa ma elekitironi ambiri komanso kutayika kochepa kwa kusinthana kuposa silicon, zomwe zimapangitsa kuti ma wafer a GaN-on-Si akhale abwino kwambiri pama circuits othamanga kwambiri.
●Kugwira Ntchito Kwambiri kwa Kutentha:Ngakhale kuti silikoni ndi yopanda kutentha, GaN-on-Si imaperekabe kukhazikika kwa kutentha kwabwino, komanso kutentha kwake kumachepa bwino kuposa zida zachikhalidwe za silikoni.
