Rov qab tawg ntawm lub diode

Rov qab kev puas tsuaj tau muab faib ua ob qhov xwm txheej: Zener tawg thiab avalanche tawg. Nyob rau hauv cov ntaub ntawv ntawm siab doping concentration, vim hais tias lub barrier cheeb tsam dav yog me me thiab qhov rov qab voltage yog loj, covalent daim ntawv cog lus cov qauv nyob rau hauv lub barrier cheeb tsam raug rhuav tshem, thiab valence electrons yog decoupled los ntawm covalent daim ntawv cog lus los tsim electron-qhov khub. , ua rau muaj kev nce ntxiv hauv tam sim no, qhov kev tawg no hu ua Zener breakdown. Yog tias qhov doping concentration tsawg, thaj tsam barrier yog qhov dav, thiab nws tsis yooj yim los ua Zener tawg.

Avalanche tawg

Lwm hom kev puas tsuaj yog kev tawg ntawm avalanche. Thaum qhov hluav taws xob rov qab tau nce mus rau tus nqi loj dua, daim ntawv thov hluav taws xob nrawm nrawm nrawm nrawm, sib tsoo nrog cov valence electrons hauv covalent daim ntawv cog lus, thiab khob cov valence electrons tawm ntawm covalent daim ntawv cog lus los tsim ib qho tshiab electron-qhov. Cov khoom siv hluav taws xob tshiab-qhov yog nrawm los ntawm qhov hluav taws xob thiab tom qab ntawd khob tawm lwm cov hluav taws xob valence. Cov neeg nqa khoom yog avalancheally nce, ua rau muaj kev nce ntxiv hauv tam sim no. Qhov kev tawg no yog hu ua avalanche breakdown. Txawm hais tias qhov tawg, yog tias qhov tam sim no tsis txwv, nws yuav ua rau muaj kev puas tsuaj mus tas li rau PN junction.
