LEEM-10 Izixhobo zoMfuniselo zePN Junction Iimpawu

Iimvavanyo

1. Kwiqondo lokushisa elifanayo, ukulinganisa phambili iimpawu ze-volt-ampere ze-PN junction kwaye ubale i-Boltzmann rhoqo;

2. I-front current ndihlala ingatshintshi, i-VT curve ye-voltage yangaphambili ye-PN junction ifakwe imephu, uvakalelo lubalwe, kunye nobubanzi be-gap ye-band yezinto ezilinganisiweyo ze-PN ziqikelelwa;

3. Uvavanyo lwesicelo: sebenzisa i-PN junction enikeziweyo ukulinganisa ubushushu obungaziwa;

4. I-innovative experiment: Ngokwedatha yovavanyo, qikelela i-reverse saturation yangoku ye-PN junction.

5. Uvavanyo lokuhlola: Qwalasela impembelelo yobungakanani bomji odibeneyo.

Iiparamitha eziphambili zobugcisa

1. Iindidi ezahlukeneyo ze-PN kunye nokupakishwa, kubandakanywa iibhubhu ze-silicon, i-germanium tubes, i-NPN transistors, njl.;

2. Uluhlu lwemveliso yangoku yi-10nA～1mA, ihlengahlengiswa kumacandelo e-4, ukulungiswa okulungileyo: ubuncinane be-1nA, i-voltage yokuqhuba

Malunga ne-5V, tsiba amagama ≤ Igama eli-1/min;

3. Ukunikezelwa kwe-ultra-high resistance 4-1 / 2 idijithi ye-voltmeter yedijithali, amanqanaba amabini okuchasana kwangaphakathi: 10MΩ, i-ultra-high resistance level (enkulu kune-1GΩ), uluhlu lokulinganisa: 0～2V, isisombululo: 0.1mV;ukungaqiniseki komlinganiselo: 0.1%± 2 amagama.

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

5. Kubandakanya isifudumezi sombane, iflaski yeDewar kunye nebeaker.
