Evaluating the thermal performance of perovskite SrSnO3 field effect transistors

July 13, 2023
Author(s)
Bivek Bista, Prafful Golani, Fengdeng Liu, Tristan Truttmann, Georges Pavlidis, Andrea Centrone, Bharat Jalan, Steven Koester
Given the ever increasing, global electricity consumption, improving the efficiency and reliability of high-power electronics is of paramount importance. Ultra-wide band gap (> 3.4 eV) semiconductors have shown the potential to be used in the next

Direct Visualization of Chemically Resolved Multilayered Domains in Mixed-Linker Metal-Organic Frameworks

June 15, 2023
Author(s)
Andrea Centrone, Belen Lerma-Berlanga, Adam Biacchi, Carmen Fernandez Conde, Georges Pavlidis, Carlos Marti-Gastaldo
The modular synthesis approach for assembling inorganic nodes and organic multidentate linkers into reticular solids enables rational engineering in porous materials known as metal-organic frameworks (MOFs). Incorporation of two or more linker types in MOF

Thermal environment impact on HfOx RRAM operation: A nanoscale thermometry and modeling study

May 8, 2023
Author(s)
Matthew West, Georges Pavlidis, Robert Montgomery, Fabia Farlin Athena, Muhammad Jamil, Andrea Centrone, Samuel Graham, Eric Vogel
As the demand for computing applications capable of processing large datasets increases, there is a growing need for new in-memory computing technologies that avoid the von Neumann bottleneck. Oxide-based resistive random-access memory (RRAM) devices are a

Beating thermal noise in a dynamic signal measurement by a nanofabricated cavity-optomechanical sensor

March 15, 2023
Author(s)
Mingkang Wang, Diego Perez Morelo, Georg Ramer, Georges Pavlidis, Jeffrey Schwartz, Liya Yu, Robert Ilic, Andrea Centrone, Vladimir Aksyuk
Thermal fluctuations often impose both fundamental and practical measurement limits on high-performance sensors, motivating the development of techniques that bypass the limitations imposed by thermal noise outside cryogenic environments. Here, we

Gate resistance thermometry: An electrical thermal characterization technique

July 15, 2022
Author(s)
Georges Pavlidis, Brian Foley, Samuel Graham
Gate Resistance Thermometry (GRT) is a potential reliable technique to determine the average temperature of the gate metal in GaN transistors. In contrast to other electrical techniques that average the temperature across different areas of the active

High throughput nanoimaging of thermal conductivity and interfacial thermal conductance

May 17, 2022
Author(s)
Mingkang Wang, Georg Ramer, Diego Perez, Georges Pavlidis, Jeffrey Schwartz, Liya Yu, Robert Ilic, Vladimir Aksyuk, Andrea Centrone
Thermal properties of materials are often determined by measuring thermalization processes. Measuring such properties at the nanoscale, however, requires high sensitivity, high temporal, and high spatial resolutions concurrently, which is beyond the

Micro to nano: multiscale IR analyses reveal zinc soap heterogeneity in a 19th-century painting by Corot

February 9, 2022
Author(s)
Xiao Ma, Georges Pavlidis, Eoghan Dillon, Victoria Beltran, Jeffrey Schwartz, Mathieu Thoury, Ferenc Borondics, Christophe Sandt, Kevin Kjoller, Barbara Berrie, Andrea Centrone
The formation and aggregation of metal carboxylates (metal-soaps) can degrade the appearance and integrity of oil paints and frequently poses a challenge to the conservation of painted works of art. Efforts to understand the root cause of metal-soap

Experimental confirmation of long hyperbolic polariton lifetimes in monoisotopic (10B) hexagonal boron nitride at room temperature

September 14, 2021
Author(s)
Georges Pavlidis, Jeffrey Schwartz, Joseph Matson, Thomas Folland, Song Liu, James Edgar, Joshua Caldwell, Andrea Centrone
Hyperbolic phonon polaritons (HPhPs) enable arbitrarily high confinements, low losses, and directional propagation – providing opportunities from hyperlensing to flat optics, and other advanced nanophotonics applications. In this work, two near-field

Revealing the distribution of metal carboxylates in oil paint from the micro- to the nanoscale

June 21, 2019
Author(s)
Xiao Ma, Victoria Beltran, Georg Ramer, Georges Pavlidis, dilworth parkinson, Mathieu Thoury, Tyler Meldrum, Andrea Centrone, Barbara H. Berrie
Oil paints comprise pigments, drying oils, and additives that together confer desirable properties, but can react forming metal carboxylates (soaps) that, over time, may damage artworks. Despite substantial research to understand these phenomena, soap

Spontaneous current constriction in threshold switching devices

April 9, 2019
Author(s)
Jonathan Goodwill, Georg Ramer, Dasheng Li, Brian Hoskins, Georges Pavlidis, Jabez J. McClelland, Andrea Centrone, James A. Bain, Marek Skowronski
Threshold switching devices exhibit extremely non-linear current-voltage characteristics, which are of increasing importance for a number of applications including solid-state memories and neuromorphic circuits. It has been proposed that such non-linear
