Sigma Aldrich Fine Chemicals Biosciences Calibration standard for h

Supplier:  Sigma Aldrich Fine Chemicals Biosciences NIST2000

This Standard Reference Material (SRM) provides the high-resolution X-ray diffraction (HRXRD) community with International System of Units (SI) [1] traceable Si (220) d-spacing in transmission surface-to-crystal-plane wafer miscut and surface-to-Si (004) Bragg angle in reflection for our reference wavelength. A unit of SRM 2000 consists of25 mm x 25 mm x 0.725 mm double-polished (100)-oriented single-crystal Si specimens with a nominal 50 nm Si0.85Ge0.15 epitaxial layer and 25 nm Si cap. These certified values can be used to calibrate HRXRD instrumentation. For more information please refer to the SDS and COA.SRM 2000cert SRM 2000 SDS
