Izinsiza Zokuhlola ze-LEEM-15 zezimpawu ze-PN Junction

Isingeniso

Izici zomzimba ze-semiconductor PN junction zingenye yezinto ezibalulekile eziyisisekelo ze-physics ne-electronics. Lezi zinsizakusebenzisa indlela yokuhlola ngokomzimba ukukala ubudlelwano phakathi kwamanje wokusabalalisa kwe-PN junction namandla, kufakazela ukuthi lobu budlelwano bulandela umthetho wokusabalalisa obonakalayo, futhi ulinganisa okungaguquguquki kweBoltzmann (esinye sezimo ezibalulekile ku-physics) ngokunembile, okwenza abafundi bafunde indlela entsha yokukala amandla abuthakathaka. Lezi zinsiza zihlinzeka ngesifudumezi esishintshanisa ukushisa kwe-thermostat ukukala ubudlelwano phakathi kwe-PN junction voltage ne-thermodynamic lokushisa T, ukuze kutholakale ukuzwela kwenzwa, futhi ulinganisele ukuthola igebe lamandla wezinto ze-silicon ku-0K. Lo mshini uzinzile futhi unokwethenjelwa, futhi unokuqukethwe okuningi kokuhlolwa komzimba, umqondo ocacile, ukwakheka kwesakhiwo okunengqondo nemiphumela yokukala ngokunemba okuphezulu. Lezi zinsiza zisetshenziswa kakhulu ekuhlolweni okujwayelekile ngokomzimba nasekuhlolweni kokucwaninga kokuqamba emakolishi nasemanyuvesi.

Ukuhlolwa

1. Ubudlelwano phakathi kwamandla wamanje we-PN junction diffusion namandla we-junction kuyalinganiswa, futhi lobu budlelwano kuzofakazelwa ukuthi bulandela umthetho wokusabalalisa obonakalayo ngokusebenzisa ukucutshungulwa kwedatha;

2. Ukuguquguquka kweBoltzmann kukalwa ngokunemba kakhudlwana (Iphutha lizoba ngaphansi kuka-2%);

3. Funda ukusebenzisa i-amplifier yokusebenza ukwakha isiguquli samanje samandla ukukala i-current weak from 10^-6A kuye ku-10^-8A;

4. Kukalwa ubudlelwano phakathi kwamandla we-PN junction voltage nezinga lokushisa nokuzwela kwamandla we-junction voltage nethempelesha kubalwa;

5. Isilinganiso sokubala igebe lamandla ento ye-semiconductor (silicon) ku-0K.

Izinkomba Zezobuchwepheshe

1. DC ugesi

Ukunikezwa kwamandla okuguquguquka okungu-0-1.5V DC;

Ukunikezwa kwamandla okushintshwa kwe-1mA-3mA DC.

2. LCD nesilinganiso module

Isilinganiso sesinqumo se-LCD: amaphikseli ayi-128 × 64

Izinkomba ezimbili zedijithali zamandla kagesi: 0-4095mV, Resolution ratio: 1mV

Ibanga: 0-40.95V, Resolution ratio: 0.01V

3. Idivayisi yokuhlola

Iqukethe i-amplifier esebenzayo i-LF356, isokhethi yesixhumi, i-potentiometer yamaphuzu amaningi, njll. I-TIP31 nohlobo lwe-9013 triode zixhunywe ngaphandle.

4. Isifudumezi

Dry kahle ithusi heater adjustable;

Ibanga lokulawula ukushisa kwe-thermostat: Ukushisa kwegumbi kuya ku-80.0 ℃;

Ukulungiswa kwesilinganiso sokulawulwa kokushisa okungu-0.1 ℃.

5. Imishini yokulinganisa izinga lokushisa

Inzwa yokushisa yedijithali ye-DS18B20
