Intshayelelo

Iimpawu zomzimba ze-semiconductor PN junction zezinye zezinto ezibalulekileyo ezisisiseko kwifiziksi nakwi-elektroniki. Esi sixhobo sisebenzisa indlela yovavanyo lomzimba ukulinganisa ubudlelwane phakathi komsinga wokusasazwa kwe-PN junction kunye ne-voltage, siqinisekisa ukuba olu lwalamano lulandela umthetho wokusasazwa kwe-exponential, kwaye silinganisa i-Boltzmann constant (enye yezona constants zibalulekileyo kwifiziksi) ngokuchanekileyo, evumela abafundi ukuba bafunde indlela entsha yokulinganisa umsinga obuthathaka. Esi sixhobo sinika i-thermostat yokutshintsha ubushushu be-heater ukulinganisa ubudlelwane phakathi kwe-PN junction voltage kunye ne-thermodynamic temperature T, ukuze kufumaneke uvakalelo lwe-sensor, kwaye kuqikelelwa ukuba kufumaneke umsantsa wamandla wezinto ze-silicon kwi-0K. Esi sixhobo sizinzile kwaye sithembekile, kwaye sinomxholo omninzi wovavanyo lomzimba, ingcamango ecacileyo, uyilo olufanelekileyo lwesakhiwo kunye neziphumo zokulinganisa ngokuchanekileyo okuphezulu. Esi sixhobo sisetyenziswa kakhulu kwizilingo zomzimba ngokubanzi kunye novavanyo loyilo kwiikholeji nakwiiyunivesithi.
