LEEM-10A Izixhobo zoMfuniselo zePN Junction Iimpawu

Inkcazelo emfutshane:

Intshayelelo

Iimpawu ezibonakalayo ze-semiconductor PN junction yenye yezinto ezisisiseko ezibalulekileyo zefiziksi kunye ne-elektroniki.Esi sixhobo sisebenzisa indlela yovavanyo lomzimba ukulinganisa unxulumano phakathi kosasazo lwangoku lwesiphambuka se-PN kunye ne-voltage, ingqina ukuba olu nxulumano lulandela umthetho wokusasazwa kwe-exponential, kwaye ilinganisa i-Boltzmann engaguqukiyo (enye yezinto ezihlala zibalulekile kwifiziksi) ngokuchanekileyo ngakumbi, eyenza abafundi bafunde indlela entsha yokulinganisa umsinga obuthathaka.Esi sixhobo sibonelela ngesifudumezi esitshintshana sobushushu be-thermostat ukulinganisa ubudlelwane phakathi kombane wokuhlangana kwe-PN kunye nobushushu be-thermodynamic T, ukuze kufumaneke uvakalelo lwenzwa, kunye noqikelelo lokufumana umsantsa wamandla wezinto zesilicon kwi-0K.Esi sixhobo sizinzile kwaye sithembekile, kwaye sinemixholo emininzi yovavanyo lomzimba, ingcamango ecacileyo, uyilo olufanelekileyo lolwakhiwo kunye neziphumo zomlinganiselo ophezulu wokuchaneka.Esi sixhobo sisetyenziswa ikakhulu kuvavanyo lomzimba jikelele kunye novavanyo loyilo lophando kwiikholeji nakwiiyunivesithi.

Iinkcukacha zeMveliso

Iithegi zeMveliso

Iimvavanyo

1. Unxulumano phakathi kwe-PN junction diffusion current kunye ne-junction voltage iyalinganiswa, kwaye olu nxulumano luya kungqinwa ukuba lulandela umthetho wokusasazwa kwe-exponential ngokucubungula idatha;

2. IBoltzmann engaguqukiyo ilinganiswa ngokuchanekileyo (Impazamo iya kuba ngaphantsi kwe-2%);

3. Funda ukusebenzisa i-amplifier yokusebenza ukwenza i-converter yangoku-voltage ukulinganisa umbane obuthathaka ukusuka kwi-10.^-6A ukuya kwi-10^-8A;

4. Ubudlelwane phakathi kombane we-PN we-junction kunye nobushushu bulinganiswa kwaye uvakalelo lwe-voltage ye-junction kunye nobushushu bubalwa;

5. Uqikelelo lokubala i-gap yamandla ye-semiconductor (silicon) imathiriyeli kwi-0K.
