1 Scope

This standard specifies the DC two probe measuring zone melting germanium ingot resistivity. This standard applies to the measurement GB/T 11071 "zone melting germanium ingot" provides resistivity trapezoidal native boat production zone melting germanium ingot, resistance Measurement range of 0.1Ω · cm ~ 100Ω · cm. Requirements of this standard zone melting germanium ingot ingot measured cross-sectional area along the length of the linear portion of the gradient, and the ingot length must be greater than the cross-section Maximum size and spacing of the probe more than three times.
