Material Measurement Laboratory /Materials Measurement Science Division

Nanomechanical Properties Group

Our group develops and provides measurement science, measurement standards, and measurement technology for various characterization techniques needed by U.S. industry to better apply materials and components in a wide range of applications.

Our group works to advance metrology and instrumentation for measuring mechanical, thermal and electrical properties, and thermodynamic behavior of bulk materials, thin films, and interfaces.  We determines and disseminates key data to establish the relationship between structure, property, and performance of materials and devices to address current and future needs in semiconductor microelectronics, energy conversion applications, climate research, and additive manufacturing.  We develop standards, reference materials, micro- and nanofabricated test devices, and analysis techniques for improving the metrological foundation of characterization methods, including X-ray diffraction, atomic force microscopy, spectroscopy- and diffraction-based strain measurements, atom probe tomography, 3D microscopy, and 3D profilometry.

Diffraction Metrology and Standards

Ongoing
Diffraction techniques can provide data on a number of sample characteristics. Therefore, the method of certification and the artifact itself are chosen to address a specific measurement issue pertinent to a diffraction experiment. NIST diffraction SRMs may be divided into five groups: Line Position

Nanoscale Property Measurements by Atomic Force Microscopy

Ongoing
Over the past several decades, Atomic Force Microscopy (AFM) has advanced from a technique used primarily for surface topography imaging to one capable of characterizing a range of chemical, mechanical, electrical, and magnetic material properties with nanometer resolution. Such characterizations

Strain Measurement for Semiconductor Devices

Ongoing
Mechanical strain is hugely important to semiconductor devices and packages while also being difficult to measure accurately. Strain is engineered into CMOS channels to improve carrier mobility for higher performance at lower power but is also intrinsically present from manufacturing processes where
