Thepa ea semiconductor PN mateano ke e 'ngoe ea lintho tsa bohlokoa tsa mantlha tsa fisiks le elektroniki. Sesebelisoa sena se sebelisa mokhoa oa ho etsa liteko tsa 'mele ho lekanya kamano lipakeng tsa phallo ea PN le matla a motlakase, e paka hore kamano ena e latela molao oa kabo o hlakileng, mme e lekanya khafetsa Boltzmann (e' ngoe ea metheo ea bohlokoa ea fisiks) hantle haholo, e lumellang baithuti ho ithuta mokhoa o mocha oa ho metha bofokoli ba hajoale. Sesebelisoa sena se fana ka mocheso oa mocheso o futhumatsang mocheso ho lekanya kamano lipakeng tsa motlakase oa PN le mocheso oa thermodynamic T, e le ho fumana kutlo ea senotlolo, le ho lekanyetsa ho fumana lekhalo la matla la lisebelisoa tsa silicon ho 0K.

Liteko

1. Kamano lipakeng tsa phallo ea phallo ea PN le matla a mateano e lekantsoe, 'me kamano ena e tla netefatsoa e latela molao oa kabo o hlakileng ka ho sebetsana le data;

2. Kamehla ea Boltzmann e lekantsoe ka nepo (Phoso e tla ba tlase ho 2%);

3. Ithute ho sebelisa seholisa-molumo se sebetsang ho etsa converter ea hajoale ea motlakase ho lekanya matla a fokolang ho tloha ho 10^-6A ho isa ho 10^-8A;

4. Kamano lipakeng tsa motlakase oa PN le mocheso e lekantsoe mme ho bonoa kutloisiso ea motlakase oa mateano le mocheso;

5. Hoo e ka bang ho bala lekhalo la matla la thepa ea semiconductor (silicon) ho 0K.

Litekanyetso tsa tekheniki

1. Phepelo ea motlakase ea DC

Phepelo ea motlakase e fetolehang ea 0-1.5V DC;

Phepelo ea motlakase ea 1mA-3mA DC e fetolehang.

2. Mojule oa litekanyo tsa LCD

LCD resolution resolution: pixels tse 128 × 64

Lipontšo tse peli tsa dijithale tsa Voltage Range: 0-4095mV, Resolution ratio: 1mV

Range: 0-40.95V, Qeto karolelano: 0.01V
