Ngowuphi umahluko phakathi kwe-n-type kunye ne-p-type semiconductors?

I-chip yefriji ye-semiconductor isetyenziswa kakhulu ebomini bethu.Kukho iintlobo ezininzi ze-semiconductor efrijini chip kwimarike.Namhlanje siza kukucacisela umahluko phakathi kwe-n-type semiconductor kunye ne-p-type semiconductor.Masikwazise ifilimu yesikhenkcisi se-Hangzhou semiconductor yakho.

1. N-uhlobo lwesemiconductor
Ii-semiconductors zohlobo lwe-N, ezaziwa ngokuba zii-semiconductors ze-elektroniki, zinokuqulunqwa nge-doping phosphorus kunye nobunye ukungcola kwi-intrinsic semiconductors.

Ngenxa yokuba ii-electron ezine ze-valence kuphela kwi-athom yokungcola e-pentavalent zinokwenza i-covalent bonds kunye nee-electron ze-valence kwii-athom ezine ze-semiconductor ezijikelezileyo, ii-electron ze-valence ezongezelelweyo zinokwenza lula ii-electron zamahhala ngenxa yokuba azibotshwanga ngamabhondi adibeneyo.Kwi-n-uhlobo lwe-semiconductors, ii-electron zamahhala zininzi zabathwali ezibonelelwa ngama-athomu okungcola, kunye nemingxuma ngabathwali abancinci benziwa yi-excitation ye-thermal.

I-athomu yokungcola yepentavalent ebonelela ngee-electron simahla iba yiyoni elungileyo ngenxa yentlawulo yayo elungileyo.Ke ngoko, i-athomu yokungcola epentavalent ikwabizwa ngokuba kukungacoceki komxhasi.

2. P-uhlobo lwesemiconductor
I-P-type semiconductors, eyaziwa ngokuba yi-hole semiconductors, yenziwe nge-doping boron, i-gallium kunye ne-indium kwi-intrinsic semiconductors.

Xa ii-athom zokungahlambuluki ezi-trivalent zenza i-covalent bonds kunye ne-athom ye-silicon, ziswele ii-electron ze-valence kwaye zishiya umngxuma kwiibhondi ezidibeneyo.Kwi-p-type semiconductors, imingxuma uninzi lwabathwali benziwa yi-doping, ngelixa ii-electron zingabathwali abambalwa abaqulunqwa yi-excitation ye-thermal.Kulula ukuba imingxunya ibambe ii-electron kwaye iguqule ii-athomu zokungcola zibe yi-ion engalunganga.Ngoko ke, ukungcola okune-trivalent kukwabizwa ngokuba yi-receptor ukungcola.

Ezi zimbini zingasentla zezomahluko phakathi kwe-n-type kunye ne-p-type semiconductors, ngoko eli nqaku liphelile, enkosi ngokufunda!
