LEEM-10A Zida Zoyesera za PN Junction Characteristics

Kufotokozera Kwachidule:

Mawu Oyamba

Zomwe zimachitika pamagawo a semiconductor PN ndi chimodzi mwazinthu zofunika kwambiri pazachilengedwe komanso zamagetsi. Chida ichi chimagwiritsa ntchito njira yoyesera yakuthupi kuyeza ubale pakati pa kufalikira kwa magetsi a PN ndi voteji, zimatsimikizira kuti ubalewu umatsatira lamulo logawa mwachangu, ndikuyesa kukhazikika kwa Boltzmann (chimodzi mwazinthu zofunika kwambiri mufizikiki) molondola, zomwe zimathandiza ophunzira kuphunzira njira yatsopano yoyezera kufooka kwapano. Chipangizochi chimapereka chotenthetsera chosinthira kutentha kuti chiyeze ubale pakati pa PN mphambano voteji ndi thermodynamic kutentha T, kuti apeze kukhudzika kwa sensa, ndi pafupifupi kupeza kusiyana mphamvu ya silicon zinthu pa 0K. Chida ichi ndi chokhazikika komanso chodalirika, ndipo chili ndi zinthu zambiri zoyesera, malingaliro omveka bwino, kapangidwe kake koyenera komanso zotsatira za kuyeza kolondola kwambiri. Chida ichi chimagwiritsidwa ntchito makamaka pakuyesa kwakuthupi komanso kuyesa kafukufuku wamakoleji ndi mayunivesite.

Zoyesera

1. Ubale pakati pa PN mphambano kufalikira panopa ndi mphambano voteji amayezedwa, ndipo mgwirizano uwu adzatsimikiziridwa kutsatira exponential kugawa lamulo kudzera processing deta;

2. Kukhazikika kwa Boltzmann kumayesedwa molondola kwambiri (Zolakwa zidzakhala zosakwana 2%);

3. Phunzirani kugwiritsa ntchito amplifier kuti mupange chosinthira chamagetsi chamakono kuti muyese mphamvu yofooka kuchokera pa 10.^-6A mpaka 10^-8A;

4. Ubale pakati pa PN mphambano voteji ndi kutentha amayezedwa ndi tilinazo pa mphambano voteji ndi kutentha masamu;

5. Pafupifupi kuwerengera mphamvu ya mphamvu ya semiconductor (silicon) zakuthupi pa 0K.

Technical Indexes

1. DC magetsi

Mphamvu yosinthika ya 0-1.5V DC;

Mphamvu yosinthika ya 1mA-3mA DC.

2. LCD kuyeza gawo

Chiyerekezo cha LCD: 128 × 64 pixels

Zizindikiro ziwiri zamagetsi zamagetsi: 0-4095mV, Resolution ratio: 1mV

Mtundu: 0-40.95V, Chiŵerengero cha kusamvana: 0.01V

3. Chipangizo choyesera

Zimapangidwa ndi amplifier yogwira ntchito LF356, socket cholumikizira, multi-turn potentiometer, etc. TIP31 ndi mtundu wa 9013 triode zimagwirizanitsidwa kunja.

4. Chotenthetsera

Unikani bwino mkuwa chosinthira chotenthetsera;

Kutentha kuwongolera osiyanasiyana thermostat: Kutentha kwa chipinda mpaka 80.0 ℃;

Kusamvana chiŵerengero cha kutentha ulamuliro 0.1 ℃.

5. Zida zoyezera kutentha

DS18B20 digito kutentha kachipangizo
