Understanding how to calculate destitivity and directivity in doped sementitors is essential for designing ementiic devices. This guide provides s practial steps to perforam these calculations based ol doping levels and material accesties.

Basics of Resistivity and Conductivity

Resistivity is a mestivure of how strongly a material opposes the flow of electric curret. Conductivity is te inverse of destitivity and indicates how easily current can pass courgh a material. Both contraties consided on te material 's composition and doping level.

Calculating Resistivity

Te destitivity ((rho)) of a doped semitistor can be calculated using thee formula:

CLAS1; CLAS1; CLAS3; CLAS3; (rho = frac {1} {q times mu times N}) CLAS1; CLAS1; CLAS3; CLAS3; CLAS3;

Where:

  • CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE3; CLANE3; CLANE3; CLANE3; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE3; CLANE3c)
  • CLANEK1; CLANEK1; CLANEK1; CLANEK1; CLANEK1; CLANEK1; CLANEK3; CLANEK3; CLANEK3; CLANEK1; CLANEK1; CLANEK1; CLANEK1; CLANEK1; CLANEK1; CLANEK1; CLANEK3; CLANEK3; CLANEK3; / V · s)
  • CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE3; CLANE3; CLANE3; CLANE1; CLANE1; CLANE3; CLANE3; CLANE3; CLANE1; CLANE1; CLANE1; CLANE1; CLANE3; CLANE3;)

By sustituting know n values, yu can determinate thee desitivity of thee doped semitiptor.

Kalkulating Reguctivity

Průvodce ((sigma)) is calculated as te reciprocal of destitivity:

CLAS1; CLAS1; CLAS3; CLAS3; (sigma = q times mu times N) CLAS1; CLAS1; CLAS3; CLAS3; CLAS3c;

This formula shows that increasing doping concentration or carrier mobility enhances dirivity.

Praktical Example

Předpokládá se, že silikonový semitor is doped with a concentration of 1 × 10 CL1; FLT: 0 CL3; FL3; 17 CL1; FLT1; FLT: 1 CL3; cm CL1; FL1; FLT1; FLT1; FLT: 3 CL3; FLT3; FL3; If the mobility of CLTIS1s 1350 cm CL1; FLT1; FLT1; FLT1; F1; FLT1s: 5 CLL3; / V · s, then:

Resistivity:

(rho = frac (1, 6 krát 10 ^ (- 19})) times 1350 times 1 krát 10 ^ (17}})

Průvodce:

CLAS1; CLAS1; CLAS3; CLAS3; (sigma = (1.6 times 10 ^ {- 19}) times 1350 times 1 times 10 ^ {17}) tis1; CLAS1; CLAS1; CLAS3FT: 1 cus3; CLAS3m;
