Measuring volume resistivity and surface resistivity of conductive materials using the four-point probe method

March 8, 2024

Four point probes are used in nanofabrication to measure the resistive properties of conducting films which may include substrates, deposited films, and doped regions on a sample surface. The four-point probe method can be used to measure volume resistivity, surface resistivity, and conductivity. The four-point probe method is the four-terminal...

Tensile Test

January 25, 2022

The basic idea of a tensile test is to place a sample of a material between two fixtures called "grips" which clamp the material. The material has known dimensions, like length and cross-sectional area.

Coefficient of friction, definition and measurement

January 10, 2020

Coefficient of Friction (COF) defifines the sliding interaction between two surfaces. Static Friction and Dynamic Friction (or Kinetic Friction) are defifined in many standards including GB10006, ASTM D1894, ISO8295, ISO15359, GB/T22895.
