Zipangizo Zoyesera za LEEM-10A za Makhalidwe a PN Junction

Kufotokozera Kwachidule:

Chiyambi

Kapangidwe ka thupi ka semiconductor PN junction ndi chimodzi mwazinthu zofunika kwambiri mu fizikisi ndi zamagetsi. Chipangizochi chimagwiritsa ntchito njira yoyesera thupi kuti chiyese ubale pakati pa mphamvu yofalikira ya PN junction ndi voltage, kutsimikizira kuti ubalewu umatsatira lamulo la kugawa kwa exponential, ndikuyesa Boltzmann constant (imodzi mwa zokhazikika zofunika mu fizikisi) molondola, zomwe zimathandiza ophunzira kuphunzira njira yatsopano yoyezera mphamvu yofooka. Chipangizochi chimapereka thermostat yosinthira kutentha kuti iyese ubale pakati pa mphamvu ya PN junction ndi kutentha kwa thermodynamic T, kuti ipeze kukhudzidwa kwa sensa, komanso pafupifupi kuti ipeze kusiyana kwa mphamvu kwa zinthu za silicon pa 0K. Chipangizochi ndi chokhazikika komanso chodalirika, ndipo chili ndi zinthu zambiri zoyesera thupi, lingaliro lomveka bwino, kapangidwe koyenera ka kapangidwe ndi zotsatira zolondola kwambiri. Chipangizochi chimagwiritsidwa ntchito makamaka muzoyesa thupi komanso zoyeserera zofufuza kapangidwe m'makoleji ndi mayunivesite.

Zoyesera

1. Ubale pakati pa mphamvu ya PN junction diffusion current ndi voltage ya junction umayesedwa, ndipo ubalewu udzatsimikiziridwa kuti ukutsatira lamulo la exponential distribution kudzera mu data processing;

2. Chosasintha cha Boltzmann chimayesedwa molondola kwambiri (Cholakwikacho chidzakhala chochepera 2%);

3. Phunzirani kugwiritsa ntchito amplifier yogwira ntchito popanga chosinthira magetsi kuti muyese mphamvu yofooka kuchokera pa 10-6A mpaka 10-8A;

4. Ubale pakati pa mphamvu ya PN junction ndi kutentha umayesedwa ndipo mphamvu ya mphamvu ya junction ndi kutentha imawerengedwa;

5. Kuyerekeza kuwerengera kusiyana kwa mphamvu kwa zinthu za semiconductor (silicon) pa 0K.

Ma Index Aukadaulo

1. Mphamvu yamagetsi ya DC

Mphamvu yamagetsi ya 0-1.5V DC yosinthika;

Mphamvu yamagetsi ya DC ya 1mA-3mA yosinthika.

2. Gawo loyezera la LCD

Chiŵerengero cha LCD resolution: 128×64 pixels

Zizindikiro ziwiri za digito za voltage Range: 0-4095mV, Chiŵerengero cha Resolution: 1mV

Kuchuluka: 0-40.95V, Chiŵerengero cha kutsimikiza: 0.01V

3. Chipangizo choyesera

Imapangidwa ndi amplifier yogwira ntchito LF356, soketi yolumikizira, potentiometer yozungulira mozungulira, ndi zina zotero. TIP31 ndi triode ya mtundu wa 9013 zimalumikizidwa kunja.

4. Chotenthetsera

Chotenthetsera chosinthika ndi mkuwa;

Kulamulira kutentha kwa thermostat: Kutentha kwa chipinda mpaka 80.0℃;

Chiŵerengero cha kusinthika kwa kutentha ndi 0.1℃.

5. Zipangizo zoyezera kutentha

Sensa ya kutentha ya digito ya DS18B20
