Inyito ya "N-type" yerekeza ku bwoko bwa doping ikoreshwa mu bikoresho bya SiC. Muri fiziki ya semiconductor, doping ikubiyemo kwinjiza imyanda mu mashini ya semiconductor nkana kugira ngo ihindure imiterere yayo y'amashanyarazi. Doping ya N-type ishyiramo ibintu bitanga electron nyinshi zigenga, bigatuma ibikoresho biba bifite ubwinshi bukabije bw'amashanyarazi.
Ibyiza by'ibice bya N-type SiC bigizwe na:
1. Imikorere y'ubushyuhe bwinshi: SiC ifite ubushyuhe bwinshi kandi ishobora gukora ku bushyuhe bwinshi, bigatuma ikoreshwa mu buryo bw'ikoranabuhanga bukoresha ingufu nyinshi kandi bukoresha inshuro nyinshi.
2. Umuvuduko mwinshi w'amashanyarazi: Ibikoresho bya SiC bifite umuvuduko mwinshi w'amashanyarazi, bigatuma bihanganira amashanyarazi menshi nta gucika kw'amashanyarazi.
3. Ubudahangarwa bw'imiti n'ibidukikije: SiC irwanya imiti kandi ishobora kwihanganira ibidukikije bikomeye, bigatuma ikoreshwa mu bintu bigoye kuyikoresha.
4. Kugabanuka k'ibura ry'ingufu: Ugereranyije n'ibikoresho bisanzwe bishingiye kuri silikoni, substrates za SiC zituma habaho guhinduranya ingufu neza kandi zikagabanya ibura ry'ingufu mu bikoresho by'ikoranabuhanga.
5. Icyuho kinini: SiC ifite icyuho kinini, gituma habaho iterambere ry'ibikoresho by'ikoranabuhanga bishobora gukora ku bushyuhe bwinshi n'ubucucike bw'ingufu nyinshi.
Muri rusange, substrates za N-type SiC zitanga inyungu zikomeye mu iterambere ry’ibikoresho by’ikoranabuhanga bikora neza cyane, cyane cyane mu bikorwa aho imikorere y’ubushyuhe bwinshi, ubucucike bw’ingufu nyinshi, no guhindura ingufu neza ari ingenzi cyane.
