Metode Experimental Measuremt

One practichal method involsuringe the dextion widtr and the built -in electric field. Teknis incudes cacacacitability -voltage (c-V) profiding and resticimene-that-voltape. Thees methode provides empicall data to estimene potential.

Praktikal Steps for Measulement

To decie the built -in potentitul experientally:

  • Siapkan p-n junction device and connect to a metrament setup.
  • Perform C-V extraments to obtain the decantion capactitance at varioos voltages.
  • Plot 1 / C 1f; FLT: 0 AF3; 2 1; 1f 1; FLT: 1 123; 133; versus voltape and find te estimate the built-is potential.
  • Alternatively, measure the terbuka-sirkuit voltape under equilibrium conditions.
