LEEM-10 Sesebelisoa sa Teko sa Litšobotsi tsa PN Junction

Liteko

1. Ka mocheso o ts'oanang, lekanya litšobotsi tsa pele tsa volt-ampere tsa motsoako oa PN 'me u bale Boltzmann kamehla;

2. Motlakase oa pele ke lula o sa fetohe, lekhalo la VT la motlakase oa pele oa PN junction le entsoe ka 'mapa, kutloisiso e baloa,' me bophara ba lekhalo la sehlopha sa lisebelisoa tse lekantsoeng tsa PN li hakanngoa;

3. Teko ea kopo: sebelisa moeli o fanoeng oa PN ho lekanya mocheso o sa tsejoeng;

4. Teko e ncha: Ho ea ka boitsebiso ba liteko, hakanya hore morao-rao oa ho phalla ke oa PN junction.

5. Teko ea ho hlahloba: Ela hloko tšusumetso ea boholo ba motlakase o kopantsoeng.

Mekhahlelo ea mantlha ea tekheniki

1. Mefuta e fapa-fapaneng ea lihlopha tsa PN tse nang le liphutheloana, ho kenyelletsa le li-tubes tsa silicon, li-tubes tsa germanium, li-transistors tsa NPN, joalo-joalo;

2. Palo ea hona joale ea tlhahiso ke 10nA～1mA, e ka fetoloa likarolong tse 4, phetoho e ntle: bonyane 1nA, motlakase oa ho khanna.

Hoo e ka bang 5V, tlōla mantsoe ≤ 1 lentsoe / min;

3. E inehetseng e phahameng ea ho hanyetsa 4-1 / 2 digital voltmeter ea dijithale, mekhahlelo e 'meli ea ho hanyetsa ka hare: 10MΩ, tekanyo e phahameng ea ho hanyetsa (e kholo ho feta 1GΩ), tekanyo ea tekanyo: 0～2V, qeto: 0.1mV;ho se tsitse ha tekanyo: 0.1% ± 2 mantsoe.

4. Mocheso oa liteko: mocheso oa kamore~99℃, thermometer ea digital: 0～100℃, qeto ea 0.1℃;

5. Ho kenyeletsoa hitara ea motlakase, flask ea Dewar le beaker.
