United States e hlahisa lisebelisoa tsa semiconductor tse nang le mocheso o phahameng oa mocheso ho hatella mocheso oa chip.
Ka keketseho ea palo ea li-transistors ka har'a chip, ts'ebetso ea komporo ea komporo e ntse e tsoela pele ho ntlafala, empa densification e phahameng e boetse e hlahisa libaka tse ngata tse chesang.
Ntle le thekenoloji e nepahetseng ea tsamaiso ea mocheso, ntle le ho fokotsa lebelo la ts'ebetso ea motlakase le ho fokotsa ho tšepahala, ho boetse ho na le mabaka a ho thibela ho futhumala ha mocheso le ho hloka matla a eketsehileng, ho theha mathata a ho se sebetse ha matla.E le ho rarolla bothata bona, Univesithi ea California, Los Angeles e ile ea hlahisa thepa e ncha ea semiconductor e nang le mocheso o phahameng ka ho fetisisa oa mocheso ka 2018, o entsoeng ka boron arsenide e se nang sekoli le boron phosphide, e tšoanang le lisebelisoa tse teng tsa ho senya mocheso tse kang daemane le silicon carbide.karo-karolelano, ka makhetlo a fetang 3 mocheso conductivity.
Ka June 2021, Univesithi ea California, Los Angeles, e sebelisitse lisebelisoa tse ncha tsa semiconductor ho kopanya le lisebelisoa tsa k'homphieutha tse matla haholo ho atleha ho thibela mocheso oa mocheso oa li-chips, kahoo ho ntlafatsa ts'ebetso ea k'homphieutha.Sehlopha sa lipatlisiso se kentse semiconductor ea boron arsenide pakeng tsa chip le mocheso oa mocheso e le motsoako oa mocheso oa mocheso le chip ho ntlafatsa phello ea mocheso oa mocheso, le ho etsa lipatlisiso mabapi le ts'ebetso ea tsamaiso ea mocheso ea mochine oa sebele.
Ka mor'a ho tlama karolo ea boron arsenide lekhalo le leholo la matla a gallium nitride semiconductor, ho ile ha tiisoa hore mocheso oa mocheso oa sebopeho sa gallium nitride / boron arsenide o ne o le holimo ho 250 MW / m2K, 'me khanyetso ea mocheso ea mocheso e fihlile boemong bo fokolang haholo.Boron arsenide substrate e tsoela pele ho kopanngoa le mochine o tsoetseng pele oa elektronike o phahameng oa mobility transistor chip o entsoeng ka aluminium gallium nitride / gallium nitride, 'me ho netefalitsoe hore phello ea ho senya mocheso e molemo haholo ho feta ea daemane kapa silicon carbide.
Sehlopha sa lipatlisiso se ile sa sebetsa chip ka tekanyo e phahameng ka ho fetisisa, 'me sa lekanya sebaka se chesang ho tloha mocheso oa kamore ho ea mocheso o phahameng ka ho fetisisa.Liphetho tsa liteko li bontša hore mocheso oa mocheso oa mocheso oa daemane ke 137 ° C, silicon carbide heat sink ke 167 ° C, 'me mocheso oa boron arsenide ke 87 ° C feela.Ts'ebetso e ntle ea mocheso oa sebopeho sena se tsoa ho sebopeho se ikhethang sa sehlopha sa phononic sa boron arsenide le ho kopanngoa ha sebopeho.Thepa ea boron arsenide ha e na feela mocheso o phahameng oa mocheso, empa hape o na le sebopeho se senyenyane sa ho hanyetsa mocheso.
E ka sebelisoa e le sekoting sa mocheso ho fumana matla a holimo a ho sebetsa a lisebelisoa.E lebeletsoe hore e sebelisoe ka nako e telele puisanong ea mohala, e nang le bokhoni bo phahameng nakong e tlang.E ka sebelisoa tšimong ea lisebelisoa tsa motlakase tse phahameng tsa maqhubu kapa liphutheloana tsa elektroniki.
