Zita rekuti "N-type" rinoreva rudzi rwekushandisa zvinodhaka zvinoshandiswa muzvinhu zveSiC. Mufizikisi yesemiconductor, kushandisa zvinodhaka kunosanganisira kuisa tsvina nemaune mu semiconductor kuti ichinje hunhu hwayo hwemagetsi. Kushandisa zvinodhaka zveN-type kunounza zvinhu zvinopa maerekitironi akawanda, zvichiita kuti zvinhu zvive negative charge carrier concentration.
Zvakanakira zveN-type SiC composite substrates zvinosanganisira:
1. Kushanda zvakanaka pakupisa kwakanyanya: SiC ine simba rekupisa rakawanda uye inogona kushanda pakupisa kwakanyanya, zvichiita kuti ive yakakodzera kushandiswa kwemagetsi ane simba rakawanda uye mafrequency akawanda.
2. Voltage yakanyanya kupwanyika: Zvinhu zveSiC zvine voltage yakanyanya kupwanyika, zvichiita kuti zvikwanise kutsungirira magetsi akawanda pasina kupwanyika kwemagetsi.
3. Kusabatwa nemakemikari uye nharaunda: SiC inodzivirira makemikari uye inogona kutsungirira mamiriro ekunze akaoma, zvichiita kuti ive yakakodzera kushandiswa mumabasa akaoma.
4. Kurasikirwa kwesimba kushoma: Zvichienzaniswa nezvinhu zvechinyakare zvakagadzirwa nesilicon, SiC substrates dzinogonesa kushandurwa kwesimba zviri nani uye dzinoderedza kurasikirwa kwesimba mumidziyo yemagetsi.
5. Kureba kwebhandi: SiC ine mukana wakakura webhandi, zvichibvumira kugadzirwa kwemidziyo yemagetsi inogona kushanda pakupisa kwakanyanya uye simba rakawanda.
Kazhinji, ma substrates emhando yeN-SiC anopa mabhenefiti makuru pakugadzira michina yemagetsi inoshanda zvakanyanya, kunyanya mumashandisirwo ayo kushanda tembiricha yepamusoro, kuwanda kwesimba rakawanda, uye kushandurwa kwesimba zvinobudirira zvakakosha.
