Metrology of the Ohm

Ongoing

The Metrology of the Ohm Project has been a leader in providing internationally consistent resistance standards that are readily available to support the scientific and industrial foundations of the U.S. economy. Through this very broad customer base, the activities of the project enable cost...

Nanoelectromagnetics

Ongoing

The primary goal of this program is metrology that enables advanced nanoscale device (including electronics, spintronics, and life science) development. Based on current trends in electronics, we are focusing on metrology for two classes of devices: (1) nanoscale devices utilizing and exploring new...

Precision Electro-Mechanical Experiments (PREME)

Ongoing

NIST-4 Kibble Balance Previously called ‘the Electronic Kilogram’ Project, a major component of PREME is the realization of SI unit of mass, the kilogram, using the NIST-4 Kibble balance, the fourth generation of Kibble balances at NIST. This is accomplished through a high-accuracy comparison of...

A 3" wafer is seen concentric with the lower plasma electrode.

Precision Materials for Quantum Devices

Ongoing

MBE System Our fabrication system is composed of ultra-high vacuum (UHV) chambers that support the in-vacuum exchange of 75 mm wafers without exposure to air as seen in Figure 1. These chambers are: (1) a deposition chamber with electron gun deposition, UHV compatible sputter guns, in situ shadow...

Quantum Conductance

Ongoing

The quantum Hall effect (QHE), and devices that exhibit it, will continue to serve as the foundation of the ohm while also expanding its territory into other SI derived units. The world adopted the quantum SI in 2019, and it remains essential that the global metrology community pushes forth and...

10 V programmable Josephson voltage standard (PJVS) and (right) PJVS cryopackaged chip, which are disseminated by the NIST standard reference instrument (SRI) program.

Quantum Voltage Project

Ongoing

Researchers in the Quantum Voltage Project develop and disseminate highly accurate instruments that exploit the quantum mechanical properties of superconductive devices known as Josephson junctions (JJs), as well as measurement techniques and best-practices for using these instruments. When a JJ is...

Quantum Waveform Metrology

Ongoing

The 2019 redefinition of the SI was motivated in part by the success of quantum electrical standards, such as those based on the Josephson and quantum Hall effects. Quantum standards enable the direct realization of physical quantities that are traceable to fundamental constants, invariant with...

Single Photonics and Quantum Information

Ongoing

One of the activities in this group is the development of single photon technologies for quantum information science and technology. We work closely with the Nanostructure Fabrication and Metrology Project on the generation of novel non-classical states of light and the detection of single photons...

Thermal Noise Metrology

Ongoing

Customer Needs Noise is a crucial consideration in designing or assessing the performance of virtually any electronic device or system that involves detection or processing of a signal. This includes communications systems, such as cellular phones and home entertainment systems, as well as systems...

Thermoelectric Measurements

Ongoing

Thermoelectric effects enable the inter-conversion of thermal and electrical energy, with applications that include solid-state waste heat recovery in engines for automotive and industrial manufacturing; power generation for aerospace, non-terrestrial exploration, and remote sensing; and...

Exploded cross section diagram representing the simplified structure layers in a MOSFET transistor.

Transport Property Measurements for Semiconductors and Energy Materials

Ongoing

The image above is an exploded cross section diagram representing the simplified structure layers in a MOSFET transistor. Thermoreflectance (TR) laser-based measurement techniques, a key focus of this project, can measure the thermal properties of substrates, thin films, multilayer structures, and...
