LEEM-15 Ongororo Zvishandiso zvePN Junction Hunhu

Nhanganyaya

Iyo yemuviri masimba e semiconductor PN mhesano ndeimwe yezvakakosha zvakakosha zviri mukati mefizikiki uye zvemagetsi. Chishandiso ichi chinoshandisa nzira yekuyedza kuyera hukama pakati pekuparadzaniswa kwazvino kwePS mharapano nemagetsi, zvinoratidza kuti hukama uhu hunotevera mutemo wekuparadzira wakakura, uye unoyera Boltzmann nguva dzose (chimwe chezvinhu zvakakosha mufizikiki) zvakanyatsonaka, izvo zvinogonesa vadzidzi kuti vadzidze nzira nyowani yekuyera iyo isina simba yazvino. Ichi chishandiso chinopa heater inoshandura tembiricha thermostat kuyera hukama pakati pePN junction voltage uye thermodynamic tembiricha T, kuti uwane kunzwisisika kwenzwi, uye fungidziro yekuwana simba gwanza resilicon zvinhu pa0K. Ichi chishandiso chakatsiga uye chakavimbika, uye chine zvakawanda zvemuviri zvekuyedza zvirimo, yakajeka pfungwa, inonzwisisika dhizaini dhizaini uye yakakwira-chaiyo yekuyera mhedzisiro. Ichi chishandiso chinonyanya kushandiswa mukuyedza kwepanyama kuyedza uye dhizaini yekutsvaga kwekuedza mumakoreji nemayunivhesiti.

Kuedza

1. Hukama huri pakati pePN junction diffusion yazvino uye junction voltage inoyerwa, uye hukama uhwu hunoratidzwa kuti hunoteedzera exponential kugovera mutemo kuburikidza nekugadziriswa kwedata;

2. Iyo Boltzmann inogara ichiyerwa zvakaringana (Iko kukanganisa kunenge kuri pasi pe2%);

3. Dzidza kushandisa anoshanda gudzazwi kugadzira yazvino-voltage shanduko kuyera isina kusimba yazvino kubva gumi^-6A kusvika gumi^-8A;

4. Hukama huri pakati pePN junction voltage uye tembiricha hunoyerwa uye nekunzwisisika kwejunction voltage netembiricha kunoverengwa;

5. Inofungidzirwa kuverenga iyo simba gapiti ye semiconductor (silicon) zvinhu pa0K.

Technical Indexes

1. DC magetsi

Simba rinogadziriswa 0-1.5V DC magetsi;

Anogadziridzwa 1mA-3mA DC magetsi.

2. LCD yekuyera module

LCD resolution resolution: 128 × 64 pixels

Zviratidzo zviviri zvemagetsi zvemagetsi Range: 0-4095mV, Resolution ratio: 1mV

Range: 0-40.95V, Resolution reshiyo: 0.01V

3. Chiedza chekuongorora

Iyo inoumbwa neanoshanda gudzazwi LF356, chinongedzo sokisi, mizhinji-dzoka potentiometer, nezvimwewo TIP31 uye mhando 9013 triode zvakabatana kunze.

4. Heater

Dry zvakanaka mhangura inogadziriswa hita;

Tembiricha yekudzora huwandu hwe thermostat: Tembiricha yekamuri kusvika 80.0 ℃;

Resolution reshiyo tembiricha kuzvidzora 0.1 ℃.

5. Tembiricha yekuyera michina
