Izixhobo zovavanyo ze-LEEM-10 zeempawu ze-PN Junction

Iimvavanyo

1. Kubushushu obufanayo, linganisa iimpawu ze-forward volt-ampere ze-PN junction uze ubale i-Boltzmann constant;

2. Umsinga ongaphambili I awutshintshi, ijika le-VT yevolthi engaphambili ye-PN junction liyachazwa, uvakalelo luyabalwa, kwaye ububanzi be-band gap yezinto ze-PN junction ezilinganisiweyo buqikelelwa;

3. Uvavanyo lokusetyenziswa: sebenzisa i-PN junction enikiweyo ukulinganisa ubushushu obungaziwayo;

4. Uvavanyo oluyintsha: Ngokwedatha yovavanyo, qikelela i-Is yangoku yokugcwala ebuyela umva ye-PN junction.

5. Uvavanyo lokuhlola: Jonga impembelelo yobukhulu bomsinga odibeneyo.

Iiparameters eziphambili zobugcisa

1. Iindidi ezahlukeneyo zee-PN junctions ezineepakethe, kuquka iityhubhu ze-silicon, iityhubhu ze-germanium, ii-NPN transistors, njl.njl.;

2. Uluhlu lwangoku lwemveliso yi-10nA～1mA, ehlengahlengiswayo kwiindawo ezi-4, uhlengahlengiso olucokisekileyo: ubuncinci i-1nA, i-voltage yokuqhuba

Malunga ne-5V, tsiba amagama ≤ igama eli-1/umzuzu;

3. I-voltmeter yedijithali ene-ultra-high ezinikeleyo ene-4-1/2 digit resistance, amanqanaba amabini okumelana kwangaphakathi: 10MΩ, inqanaba lokumelana eliphezulu kakhulu (elingaphezulu kwe-1GΩ), uluhlu lokulinganisa: 0～2V, isisombululo: 0.1mV; ukungaqiniseki kokulinganisa: 0.1%± amagama ama-2.

4. Ubushushu bovavanyo: ubushushu begumbi ～99℃, i-thermometer yedijithali: 0～100℃, isisombululo 0.1℃;

5. Kubandakanya i-heater yombane, iflaski yeDewar kunye ne-beaker.
