Izixhobo ze-semiconductor ziye zanda kakhulu kubuchwepheshe banamhlanje, zinika amandla yonke into ukusuka kwiifowuni eziphathwayo ukuya kwizithuthi zombane. Njengoko imfuno yezixhobo ze-elektroniki ezisebenzayo nezinamandla iqhubeka isanda, iteknoloji ye-semiconductor iyaqhubeka nokutshintsha, abaphandi behlola izixhobo ezintsha kunye nezakhiwo ezinokubonelela ngokusebenza okuphuculweyo. Enye into esandul 'ukutsala ingqalelo yamandla ayo kwizixhobo ze-semiconductor yi-granite. Nangona i-granite isenokubonakala ngathi lukhetho olungaqhelekanga kwizixhobo ze-semiconductor, ineempawu ezininzi ezenza ukuba ibe lukhetho olunomtsalane. Nangona kunjalo, kukwakho nemida ethile enokubakho ekufuneka iqwalaselwe.
I-Granite luhlobo lwelitye eliyi-igneous elenziwe ngeeminerali eziquka i-quartz, i-feldspar, kunye ne-mica. Iyaziwa ngamandla ayo, ukuqina kwayo, kunye nokumelana nokuguguleka, okwenza ukuba ibe yinto yokwakha ethandwayo kuyo yonke into ukusuka kwizikhumbuzo ukuya kwiikhawuntara zasekhitshini. Kwiminyaka yakutshanje, abaphandi bebehlola amandla okusebenzisa i-granite kwizixhobo ze-semiconductor ngenxa yokuqhuba kwayo ubushushu obuphezulu kunye ne-coefficient ephantsi yokwandiswa kobushushu.
Ukuqhuba ubushushu bubuchule bezinto ezisetyenziswayo ukuhambisa ubushushu, ngelixa i-thermal expansion coefficient ibhekisa ekubeni izinto ziya kwanda okanye zinciphe kangakanani xa ubushushu bazo butshintsha. Ezi mpawu zibalulekile kwizixhobo ze-semiconductor kuba zinokuchaphazela ukusebenza kakuhle kunye nokuthembeka kwesixhobo. Ngenxa yokuqhuba ubushushu okuphezulu, i-granite iyakwazi ukukhupha ubushushu ngokukhawuleza, nto leyo enokunceda ukuthintela ubushushu obugqithisileyo kunye nokwandisa ubomi besixhobo.
Enye inzuzo yokusebenzisa igranite kwizixhobo ze-semiconductor kukuba yinto yendalo, oko kuthetha ukuba ifumaneka lula kwaye ayibizi kakhulu xa ithelekiswa nezinye izinto ezisebenza kakuhle njengedayimani okanye i-silicon carbide. Ukongeza, igranite izinzile ngokweekhemikhali kwaye ine-dielectric constant ephantsi, enokunceda ukunciphisa ukulahleka kwesignali kunye nokuphucula ukusebenza kwesixhobo ngokubanzi.
Nangona kunjalo, kukwakho nemida ethile enokuthi iqwalaselwe xa usebenzisa i-granite njengesixhobo se-semiconductor. Omnye wemingeni ephambili kukufezekisa izakhiwo zekristale ezikumgangatho ophezulu. Ekubeni i-granite ililitye elivela ngokwendalo, inokuqulatha ukungcola kunye neziphene ezinokuchaphazela iimpawu zombane kunye nezokukhanya zezinto. Ngaphezu koko, iimpawu zeentlobo ezahlukeneyo ze-granite zinokuhluka kakhulu, nto leyo enokwenza kube nzima ukuvelisa izixhobo ezihambelanayo nezithembekileyo.
Omnye umceli mngeni wokusebenzisa i-granite kwizixhobo ze-semiconductor kukuba yinto ebuthathaka xa ithelekiswa nezinye izinto ze-semiconductor ezifana ne-silicon okanye i-gallium nitride. Oku kunokuyenza ibe lula ukuqhekeka okanye ukuqhekeka phantsi koxinzelelo, nto leyo enokuba yingxaki kwizixhobo eziphantsi koxinzelelo loomatshini okanye ukushaqeka.
Nangona le mingeni, iingenelo zokusebenzisa igranite kwizixhobo ze-semiconductor zibaluleke ngokwaneleyo kangangokuba abaphandi bayaqhubeka nokuhlola amandla ayo. Ukuba le mingeni inokoyiswa, kunokwenzeka ukuba igranite inokubonelela ngendlela entsha yokuphuhlisa izixhobo ze-semiconductor ezisebenza kakuhle nezingabizi kakhulu ezizinzileyo kwindalo esingqongileyo kunezixhobo eziqhelekileyo.
Ukuqukumbela, nangona kukho imida ethile enokubakho ekusebenziseni i-granite njengesixhobo se-semiconductor, ukuhanjiswa kwayo kobushushu obuphezulu, i-coefficient yokwandisa ubushushu obuphantsi, kunye ne-dielectric constant ephantsi kwenza ukuba ibe lukhetho olunomtsalane kuphuhliso lwesixhobo sexesha elizayo. Ngokujongana nemingeni enxulumene nokuvelisa izakhiwo zekristale ezikumgangatho ophezulu kunye nokunciphisa ukubhitya, kunokwenzeka ukuba i-granite ingaba yinto ebalulekileyo kushishino lwe-semiconductor kwixesha elizayo.
