2- and 4-Terminal Method

A normal multimeter, equipped with 2 terminals, is a cheap and simple instrument for measuring voltage, current and resistance. However, the conventional 2-terminal method is not suitable for material evaluation. …

Conductivity (σ)

Conductivity (σ) is inversely related to volume resistivity. It is also called specific conductivity. The unit is S/cm. Conductivity σ [S/cm] =(1 / pv)

Waht is Surface Resistivity (ps) ?

ρs is the resistance per unit surface of a sample and is also called sheet resistance. In order to distinguish this from resistance, it is written Ω/□ or Ω/sq.. Since …

Resistivity Correction Factor (RCF)

The Resistivity Correction Factor (RCF) is changed with the sample shapes and sizes as well as measuring positions. In the 4-pin probe method, since the sample size or measuring position …

What is Volume Resistivity ?

Volume Resistivity ( ρv ) expresses the resistance per unit volume of a sample and is also called specific resistance. It is the term mostly used for material classification (Ω∙cm). …
