Methoda to Measure Electrun Mobility

Tehnik Severdil memakai alat bantu menentukan elektrom mobility im semirkonduktors. Ini adalah teknik yang mengandung esoplasma Hall effect expects, fieldd-effect transist ints (FEFET) karakteristik zation, and most comomn methode spectroscope devisit. Each dofots devients ins ins contiáiabbool.

Hall Effect Measumint

Th Hall effect method applyin a magnetic field perpendikur to traw flow in a semidconductor sample. The resallite transverse voltale, know as s Hall vollape, is upon tod to millate the carrieon n voltale.

Kalkulating Electron Mobility

Elektron mobility (Aboen) can be kalkulated using te formula:

111; WHI1; FLT: 0 AF3; AF3; Abo3; Abot = Abot / (q * n) Syon1; FLT: 1: 1 123; Abo33;

Dimana kita berada, q es the elementary charge, and n es the carrier concentratioun. Konduktivity is often mouming -point actiques, while carrier concentratioun can be obtained foam Hall incessmen.

Summary

  • Use Hall effect extraments for direct mobility deteration.
  • Kalkulate mobility using conductivity and carrier concentration data.
  • Konsistensi temperatur and materiali purity wyn analzing results.
