Electronic Material Characterization

Ongoing
Manufacturing optimized devices that incorporate newly-emerging materials requires predictable performance throughout device lifetimes. Unexpected degradation in device performance, sometimes leading to failure, is often traceable to poor material reliability. Reliability is rooted in the stability...

Electronics for Cryogenic Environments

Ongoing
The operation of electronics optimized for room temperature applications in cryogenic environments introduces a remarkable number of physical and engineering hurdles. It is unsurprising that devices and circuits designed for room temperature encounter shifts in their operation parameters in...

Emerging Power Electronic Devices

Ongoing
The ongoing electrification of society has elevated the importance of electric transportation, renewable energy distribution, and data centers. It has also put new demands on the technologies -- called power electronics -- that control, interface, and transmit the electrical energy that powers our...

Engineered Designer Lattices for Quantum Systems

Ongoing
Exposing the low-dimensional materials to a superlattice periodic potential is an effective way to engineer their electronic and other solid-state properties. One example is the moiré superlattice, created by stacking two-dimensional layers at a twist angle, which leads to novel band structures and...

Femtosecond Nonlinear Optical Spectroscopy of Nanoscale Materials

Ongoing
The purpose of this project is to develop and refine spectroscopic techniques based on nonlinear optics for the study of novel materials. Measurements that isolate the nonlinear response are often better able to uncover physical processes that, in the linear response, are subtle and hard to isolate...

Graphene

Ongoing
Two remarkable features of graphene that are opening avenues to multiple applications are its high transport carrier mobility and the broad tunability of its electronic properties. Graphene charge carriers can be tuned continuously from negative carriers (i.e., electrons) to positive carriers (holes...

Hardness Standardization and Measurements

Ongoing
DESCRIPTION Purpose: Provide measurement traceability for the Knoop, Rockwell, and Vickers hardness scales and for coating thickness measurements that are based on magnetic methods. Goals: Harmonization of hardness and coating thickness testing protocols, in pursuit of reduction of measurement...

High Temperature Hall Effect Measurements

Ongoing
Customized Hall effect measurement apparatus which supports measures of Hall effect mobility and resistivity of semiconducting films across a wide range of temperatures (77K-825K).

Illicit Narcotics Detection

Ongoing
“Method for evaluating ion mobility spectrometers for trace detection of fentanyl and fentanyl-related substances”, Jennifer R Verkouteren, Jeffrey Lawrence, R Michael Verkouteren and Edward Sisco, Analytical Methods, 11(47), 6043-6052 (2019). “Discriminative potential of ion mobility spectrometry...

Inorganic Phase Equilibrium Data

Ongoing
Every deliberate effort to develop a new material or to improve processing begins with chemical composition and the conditions (temperature, pressure) under which pure compounds and their mixtures are stable ( an equilibrium phase diagram ). In the absence of such information, materials scientists...

Ion Mobility Spectrometry

Ongoing
IMS employs a drift tube with an applied electric field to separate ionized molecules based on their mobility. The technique is robust and capable of differentiating a wide range of drug and explosive molecules. Recent work has sought to investigate the utility of IMS for screening of illicit...

Magnetic Imaging

Completed
Advanced magnetic devices and storage media will rely on ultra thin ferromagnetic films; since such films are quasi two-dimensional magnets, they can have strong perpendicular magnetic anisotropy (PMA). Optimization of future materials, including improved yields, requires an ability to measure film...

Magnetic Sector Secondary Ion Mass Spectrometry

Ongoing
Magnetic sector SIMS uses high energy “primary” ions to bombard the surface and liberate “secondary” ions much like in ToF-SIMS, but the ion beam is operated continuously to maximize duty cycle. The high ion dose is preferred for depth profiling, where the concentration of elements and isotopes are...

Measurements of Point-Defect Chemistry in Complex Oxides

Ongoing
Project Goal: To develop magnetic resonance, x-ray absorption, electron diffraction, and electrical conductivity measurements to better characterize dilute concentrations of point defects in oxide materials and effectively correlate electro-mechanical properties to measured defect chemistry. Oxide...

Measuring Intermolecular Interactions with Electro-Acoustic Spectroscopy

Ongoing
We have a number of opportunities to collaborate with us. See below for details. What does this project aim to do for the chemical industry? Many industrial processes depend on the intermolecular environment- the solvents and ions that surround a molecule. These interactions impact separations...
