LEEM-10 Kuedza Zvishandiso zvePN Junction Hunhu

Miedzo

1. Patembiricha imwe chete, pima kumberi kwevolt-ampere maitiro ePN junction uye verenga iyo Boltzmann isingachinji;

2. Ikozvino mberi ini ndinoramba ndisina kuchinjwa, VT curve yevheji yepamberi yePN junction yakarongwa, kunzwisiswa kunotarwa, uye bhendi gap upamhi hweiyo yakayerwa PN junction zvinhu inofungidzirwa;

3. Kuedza kwekushandisa: shandisa yakapihwa PN junction kuyera tembiricha isingazivikanwe;

4. Kuedza kutsva: Maererano ne data yekuedza, fungidzira reverse saturation ikozvino Ndiyo yePN junction.

5. Chiedzo chekuongorora: Cherekedza kurudziro yehukuru hwezvinoumbwa zvino.

Iyo huru yehunyanzvi parameters

1. Kusiyana kwakasiyana-siyana kwePN kusanganiswa nekuputira, kusanganisira silicon tubes, germanium tubes, NPN transistors, nezvimwewo;

2. Ikozvino inobuda huwandu ndeye 10nA～1mA, inogadziriswa muzvikamu zvina, kugadzirisa kwakanaka: zvishoma 1nA, kutyaira kwekufambisa.

Nezve 5V, svetuka mazwi ≤ 1 izwi / min;

3. Yakatsaurirwa ultra-high resistance 4-1 / 2 digit digital voltmeter, mazinga maviri ekupikisa kwemukati: 10MΩ, ultra-high resistance level (yakakura kupfuura 1GΩ), chiyero chekuyera: 0～2V, kugadzirisa: 0.1mV;kuyerwa kusava nechokwadi: 0.1% ± 2 mazwi.

4. Kuedza tembiricha: kamuri tembiricha～99℃, digital thermometer: 0～100℃, resolution 0.1℃;

5. Kusanganisira hita yemagetsi, Dewar flask nebeaker.
