LEEM-10 Midziyo Yekuyedza yePN Junction Hunhu

Kuedza

1. Patembiricha imwe chete, yera hunhu hwemberi hwevolt-ampere hwePN junction uye verenga Boltzmann constant;

2. Forward current I haichinje, VT curve ye forward voltage yePN junction inorongwa, sensitivity inoverengwa, uye hupamhi hweband gap yezvinhu zvakayerwa zvePN junction hunoongororwa;

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

4. Kuedza kwekuvandudza: Zvichienderana nedata rekuyedza, fungidzira reverse saturation current Is yePN junction.

5. Kuedza kwekuongorora: Tarisa simba rehukuru hwesimba remagetsi rinobatanidza.

Huru tekinoroji parameters

1. Mhando dzakasiyana dzePN junctions dzine mapakeji, dzinosanganisira machubhu esilicon, machubhu egermanium, maNPN transistors, nezvimwewo;

2. Huwandu hwezvinobuda i10nA～1mA, inogadziriswa muzvikamu zvina, inogadziriswa zvishoma: 1nA shoma, voltage yekutyaira

Inenge 5V, siya mazwi ≤ izwi rimwe/miniti;

3. Dhijitari voltmeter ine resistance yakakura kwazvo ine madhijitari 4-1/2, mazinga maviri e resistance yemukati: 10MΩ, resistance level yakakura kwazvo (inopfuura 1GΩ), chiyero chekuyera: 0 ～ 2V, resolution: 0.1mV; chiyero chisina chokwadi: 0.1% ± mazwi maviri.

4. Tembiricha yekuyedza: tembiricha yemukamuri～99℃, thermometer yedhijitari: 0～100℃, resolution 0.1℃;

5. Kusanganisira hita yemagetsi, chirongo cheDewar nebeaker.
