About Ohm-centimetres
The ohm-centimetre (Ω·cm) equals 0.01 Ω·m, the most widely used unit for semiconductor resistivity in device characterisation. Silicon wafers are specified in Ω·cm: lightly doped n-type Si is 100-10 000 Ω·cm; device-grade p-type Si is 1-50 Ω·cm; germanium is ≈0.46 Ω·cm. ASTM F84 and SEMI standards define silicon resistivity measurements in Ω·cm. 1 Ω·cm = 0.01 Ω·m.
About Gigaohm-metres
The gigaohm-metre (GΩ·m) equals 10⁹ Ω·m, the scale for excellent insulating materials and ultra-pure liquids. Fused silica (quartz glass) has resistivity ≈ 10⁴-10⁵ GΩ·m at room temperature; ultra-pure deionised water is ≈18 MΩ·cm = 180 kΩ·m; synthetic sapphire is ≈1-10⁴ GΩ·m depending on temperature. 1 GΩ·m = 10⁹ Ω·m = 10³ MΩ·m.
