unilateral conductivity
Thaum qhov hluav taws xob pem hauv ntej tau thov rau PN kev sib tshuam, muaj peev xwm muaj lub zog loj rau sab nraud tam sim no, uas yog, tsis kam tiv taus. Peb hu rau PN hlaus kev sib txuas; thaum lub tshuab hluav taws xob thim rov qab rau PN kev sib tshuam, tsuas muaj kev hloov me me tsis pub tam sim no, qhia kev ua haujlwm siab, Peb hu rau PN hlws tawm. Qhov no yog unidirectional conductivity ntawm PN hlws ris.
