LEEM-10 Qalabka Tijaabada ee Astaamaha Isgoysyada PN

Tijaabooyin

1. Heerkul isku mid ah, cabbir sifooyinka volt-ampere hore ee isku xirka PN oo xisaabi joogtada Boltzmann;

2. Hadda hore ee aan isbeddelin, qalooca VT ee korantada hore ee isku xirka PN waa la sawiray, dareenka ayaa la xisaabiyaa, iyo ballaca farqiga band ee walxaha isku-xidhka PN ee la qiyaasay;

3. Tijaabada codsiga: isticmaal isgoysyada PN ee la bixiyay si aad u cabbirto heerkulka aan la garanayn;

4. Tijaabo hal abuur leh: Marka loo eego xogta tijaabada ah, qiyaas celceliska buuxsanaanta gadaasha ee hadda Is of the PN junction.

5. Tijaabo sahamin ah: U fiirso saamaynta cabbirka hadda la isku daray.

Qodobbada ugu muhiimsan ee farsamada

1. Kala duwanaansho kala duwan oo PN ah oo leh baakado, oo ay ku jiraan tuubooyinka silikon, tuubooyinka germanium, transistor NPN, iwm.;

2. Kala duwanaanshaha hadda jira waa 10nA～1mA, lagu hagaajin karo 4 qaybood, hagaajinta wanaagsan: ugu yaraan 1nA, korantada wadista

Qiyaastii 5V, ka bood erayada ≤ 1 kelmad/daqiiqo;

3. Iska caabin ultra-sare ah oo go'an 4-1 / 2 voltmeter dhijitaalka ah, laba heer oo iska caabin gudaha ah: 10MΩ, heerka caabbinta ultra-sare (ka weyn 1GΩ), cabbirka cabbirka: 0～2V, xallinta: 0.1mV;hubin la'aanta cabbiraadda: 0.1%± 2 erey.

4. Heerkulka tijaabada: heerkulka qolka～99℃, heerkulbeeg dhijitaal ah: 0～100℃, xallinta 0.1℃;

5. Oo ay ku jiraan kuleyliyaha korontada, weelka Dewar iyo biraha.
