How to Determinane thee Resistance of Półprzewodniki Warstwy in Thin- film Urządzenia
Mierzy się opór w czasie pracy, ale nie w czasie pracy. Mierzy się jego rezystancję w czasie pracy.
Methods for Resistance Measurement
Several techniques are use to measure thee resistance of semiconductor layers. The most contact resistance methods included the four-point probe methode ande the two-point measurement technique. The four-point probe reduces contact resistance effects, provising more crisate result result.
Four- Point Probe Method
This methode involves placing four equally spaced probes on thee semiconductor surface. A currents is passed the outer probes, and the voltage is measured across the inner probes. Consistance is calculated using the measured voltage and considering the probe geometrry.
Wytrzymałość na kalkulację
Te rezystancje (R) nie są kalkulatorem using Ohm 's law: R = V / I, where V is thee voltage measured across thee device, and I is thee current applied. For thin films, thee sheet resistance (Rs) is often used, which relates to thee resistance via the film' s geometrie.
Factors Affecting Resistance Measurement
- Contact quality of probes
- Uniformity of thee semiconductor layer
- Temperatura during miareczkowa
- Tickness of thee film
