Ilanga likhanya kwi-semiconductor ye-PN junction, lenza isibini esitsha somngxuma-electron. Ngaphantsi kwesenzo sombane wombane we-PN junction, umgodi uphuma kwindawo ye-P ukuya kwindawo ye-N, kwaye i-electron ihamba ukusuka kummandla we-N ukuya kwindawo ye-P. Xa isekethe iqhagamshelwe, ikhoyo ngoku...Funda ngokugqithisileyo
