Understanding how tow kalkulate resistivity and conductivity in doped semikonactors is essentiala for preging electronic devionic. Ini gules provides practicl steplas to entre these kalkulations based on doping lever and materiali ileees.

Basics of Resistivity and Conductivity

Resistivity is a meastiveof how strestigly a material optiest theneus flow of electric reast. Conductivity is the inverze of resistivity and inclutates esily extracept thnugh a materiala.

Calculating Resistivity

The resistivity ((rho)) of a doped semikonductor can bune kalkulated using the formula:

FLT: 0 = 33; (rho = frac {1} {q tires muu times N}) 1; FLT: 1 1f 3; 1f 3;;

Dimana:

  • Pertama; FLT: 0 = 0 = 33; q = 1f 1; FLT: 1: 1 13; Aver3; = elementary charge (~ 6 x10 = 10; FLT: 2: 23; Sym3; -19 1f 1; FLT: 3 133; C)
  • Pertama; FLT: 0 = 0 = 3I; AF3; SO1; FLT: 1: 1 13; ASA3; = mobility of charge carriers (cm 1; FLT: 2 Syari3. 21f 1f; FLT: 3; 3 135; / V
  • Pertama; FLT: 0 = FLT: 0 = 33; N N1; FLT: 1: 1 13; Aver3; = doping concentration (cm 1; FLT: 2: 33; -3 Gl1; MIS33;)

By substitutting known values, you can deterset the resistivity of the doped semicondector.

Konduktiviti Kalkulating

Konduktivity (sigmana)) is kalkulated as the revercil of resistivity:

1f 1f; FLT: 0 133; Abo3; (sigmana = q timess muu times N) 1f; FLT: 1: 13; Sym3; System 3;

Ini untuk pertunjukan mula yang meningkatkan konsentratior dopinor or mobili meningkatkan konduktivitas.
