Integrated Near-field Optoelectronic (INFO) Scanning Probe

Ongoing

In a collaboration between the Nanoelectromagnetics Project and the Quantitative Imaging Project, we have fabricated and tested a GaN nanowire mounted on an AFM tip as a near-field scanning microwave microscopy (NSMM ) tip (see Fig. 2(a) below ). A tungsten atomic layer deposition (ALD) coating

Integrated Optical Atomic Devices

Ongoing

The NIST on a Chip project in the Atomic Devices and Instrumentation group is focused on the development of compact, manufacturable, low power, SI-traceable calibration instruments using atomic vapor cells. We anticipate such devices could be broadly used in industrial settings for in-situ

Integrated Photonics

Ongoing

The Integrated Photonics Project utilizes heterogeneous materials integration to demonstrate novel optoelectronic devices such as semiconductor lasers, wavelength converters, and polarization rotators with compact form. We use materials including silicon, silicon dioxide, tantalum pentoxide, and

Integrated Testbeds for Advanced Metrology

Ongoing

Crossbar Memory Arrays An especially prolific structure in memory architectures aimed at accelerating neural network operation is the crossbar array (Fig. 1). We produce medium-scale arrays that hold up to 20,000 nanodevices which can be characterized, read from, and written to individually or in

Intelligent Building Agents

Ongoing

Objective Demonstrate the feasibility of AI control techniques for reducing the energy costs of HVAC systems in commercial buildings and create a research infrastructure, the Intelligent Building Agents Laboratory (IBAL), suitable for ongoing demonstration, development, and evaluation of advanced AI

Image of the sun at 33.5 nm on 2011-09-06.

Intercomparison of satellite instrument calibrations at SURF III/NIST and MLS/PTB

Ongoing

Solar-observing instruments operated in space degrade over time. Decades of research and engineering skill have improved protecting such optics, but one crucial solution to address instrument degradation is to regularly recalibrate the instruments to accommodate such changes. Once in orbit

Interdisciplinary Projects

Ongoing

Current: DARPA CCU (Computational Cultural Understanding) Past: IARPA MATERIAL (Machine Translation for English Retrieval of Information in Any Language) DARPA LORELEI (Low Resource Languages for Emergent Incidents) and LoReHLT (Low Resource Human Language Technologies) DARPA BOLT (Broad

Interdomain Distance Measurements of Monoclonal Antibodies

Ongoing

Through collaboration with researchers at the Institute for Biotechnology and Bioscience Research (IBBR), we have created a library of site-specific spin-labeled and stable isotope-labeled binding partner proteins for the NIST monoclonal antibody (NISTmAb) reference material ( RM8671). Using pulsed

Interfacial thermodynamics of 2D-materials-based nanofluidic systems

Ongoing

Recent experiments have demonstrated that atomically symmetric sub-nanoscale pores can be fabricated in graphene, hexagonal boron nitride, molybdenum disulfide (MoS 2), as well as in other 2D materials. This development provides an intriguing bridge between nanofluidics and coordination chemistry, a

Interferometry: Crystal Structure Factors Determined using Pendellösung Interference

Ongoing

Crystal structure factors (F Q) describe the interaction of lattices with diffracting radiation. They include a scattering amplitude term, a correction for atomic thermal motion called the Debye-Waller factor, and are dependent on the momentum transfer Q = k initial - k final. Tens of x-ray

GadInk filled neutron transmission grating

Interferometry: INFER - Neutron Interferometric Microscopy of Small Forces and Hierarchical Structures

Ongoing

Multi-scale Images and Hierarchical Structures One of the keys identified by the 2015 DOE report, “Challenges at the Frontiers of Matter and Energy: Transformative Opportunities for Discovery Science” are methods that can study hierarchical systems. Such systems include the propagation of

Interferometry: Neutron Interferometry with Polarized Neutrons as an Additional Degree of Freedom

Completed

Neutron interferometers measure the quantum entanglement between two neutron states traveling along separate paths. The quantum entanglement is generated using diffraction in crystal lattices. Crystal imperfections effectively cause quantum state noise and lowers the achievable state separation from

Interferometry: Precision Scattering Length Measurements of Low-Z Isotopes using Neutron Interferometry

Ongoing

The neutron-nucleus interaction potential can be described by a constant with the dimension of length called the neutron scattering length. In general, the scattering length (b) is spin-dependent, a complex number, and most importantly isotope-dependent. Neutron scattering lengths are fundamental in

Interferometry: Quantum Error Coding in a 4-Blade Neutron Interferometer

Completed

Single crystal neutron interferometers are extremely sensitive to environmental noise, including vibrations. This sensitivity is a result of slow neutron velocity and the long measurement times. Most neutron interferometers require vibration isolation. Usually, massive systems are employed to damp

Interferometry: Studying Quantum Materials using Neutron Interferometry

Ongoing

Neutron interferometry using perfect-silicon single crystals is a precision measurement technique that combines the neutron’s unique quantum nature with the neutron’s diverse set of interactions. Interferometry has traditionally been used in fundamental physics applications. However, there is

Interferometry: Three-Dimensional Visualization of Magnetic Skyrmions

Ongoing

Magnetic Skyrmions are localized regions in a material where the atomic spins exhibit a defect swirling pattern (topological change equal to one). Skyrmions are unique because they behave like tiny, stable particles and require only ultralow current densities to manipulate. This makes them ideal

Interlaboratory Comparison Exercises for Organic Contaminants and Trace Elements in Marine Sediments and Tissues

Completed

NIST helps benchmark and improve the quality of analytical data gathered on the marine environment by administering annual interlaboratory comparison exercises. The ability to accurately determine organic and inorganic contaminants in a wide range of marine sample types is required to assess their

International Collaborations to Improve the Accuracy of Gas Primary Standards

Ongoing

The goal is to use the results from intercomparisons to assist in determining and correcting any large differences between gas standards from different NMIs. When results are within the stated uncertainty bounds, then the NMIs gas standards are considered to be equivalent. This enables the use of

International Comparisons for Chemical Measurements

Ongoing

International agreements and decisions concerning trade and our social well-being increasingly require mutual recognition of measurements and tests among nations. The Mutual Recognition Arrangement (MRA) on national measurement standards and calibration and measurement certificates issued by NMIs
