Imishini Yokuhlola ye-LEEM-10 Yezimpawu ze-PN Junction

Ukuhlolwa

1. Ngesikhathi esifanayo sokushisa, kala izici ze-forward volt-ampere ze-PN junction bese ubala i-Boltzmann constant;

2. Ugesi wangaphambili I awushintshi, ijika le-VT le-voltage yangaphambili ye-PN junction liyahlelwa, ukuzwela kubalwa, futhi ububanzi be-band gap yezinto ezilinganiselwe ze-PN junction buyalinganiswa;

3. Ukuhlolwa kokusetshenziswa: sebenzisa i-PN junction enikeziwe ukukala izinga lokushisa elingaziwa;

4. Ukuhlolwa okusha: Ngokusho kwedatha yokuhlola, linganisa i-reverse saturation current Is ye-PN junction.

5. Ukuhlolwa kokuhlola: Bheka ithonya lobukhulu bomsinga ohlanganisiwe.

Amapharamitha obuchwepheshe ayinhloko

1. Izinhlobonhlobo ze-PN junctions ezine-package, kufaka phakathi amashubhu e-silicon, amashubhu e-germanium, ama-NPN transistors, njll.;

2. Ububanzi bokukhipha bamanje buyi-10nA～1mA, bulungiseka ngezigaba ezi-4, ukulungiswa okuncane: ubuncane be-1nA, i-voltage yokushayela

Cishe u-5V, yeqa amagama ≤ igama/umzuzu o-1;

3. I-voltmeter yedijithali enezinombolo ezingu-4 1/2 yokumelana okuphezulu kakhulu, amazinga amabili okumelana kwangaphakathi: 10MΩ, izinga lokumelana okuphezulu kakhulu (elingaphezu kuka-1GΩ), ububanzi bokulinganisa: 0 ～2V, isixazululo: 0.1mV; ukungaqiniseki kokulinganisa: 0.1% ± amagama angu-2.

4. Izinga lokushisa lokuhlola: izinga lokushisa legumbi～99℃, i-thermometer yedijithali: 0～100℃, isixazululo esingu-0.1℃;

5. Kubandakanya i-heater kagesi, i-Dewar flask kanye ne-beaker.
