Visualizing Thermally Activated Memristive Switching in Percolating Networks of Solution‐Processed 2D Semiconductors

Vinod K. Sangwan, Sonal V. Rangnekar, Joohoon Kang, Jianan Shen, Hong‐Sub Lee, David Lam, Junhua Shen, Xiaolong Liu, Ana C. M. Moraes, Lidia Kuo, Jie Gu, Haihua Wang & Mark C. Hersam
Memristive systems present a low-power alternative to silicon-based elec-tronics for neuromorphic and in-memory computation. 2D materials have been increasingly explored for memristive applications due to their novel biomimetic functions, ultrathin geometry for ultimate scaling limits, and potential for fabricating large-area, flexible, and printed neuromorphic devices. While the switching mechanism in memristors based on single 2D nanosheets is similar to conventional oxide memristors, the switching mechanism in nanosheet composite films is complicated by the interplay of...

Thermoreflectance Imaging of (Ultra)wide Band-Gap Devices with MoS2 Enhancement Coatings

Riley Hanus, Sonal V. Rangnekar, Shahab Mollah, Kamal Hussain, Nicholas Hines, Eric Heller, Mark C. Hersam, Asif Khan & Samuel Graham
Measuring the maximum operating temperature within the channel of ultrawide band-gap transistors is critically important since the temperature dependence of the device reliability sets operational limits such as maximum operational power. Thermoreflectance imaging (TTI) is an optimal choice to measure the junction temperature due to its submicrometer spatial resolution and submicrosecond temporal resolution. Since TTI is an imaging technique, data acquisition is orders of magnitude faster than point measurement techniques such as Raman thermometry. Unfortunately,...

First Demonstration of Tuning Between the Kitaev and Ising Limits in a Honeycomb Lattice

Faranak Bahrami, Xiaodong Hu, Yonghua Du, Oleg I. Lebedev, Chennan Wang, Hubertus Luetkens, Gilberto Fabbris, Michael J. Graf, Daniel Haskel, Ying Ran & Fazel Tafti
Recent observations of novel spin-orbit coupled states have generated tremendous interest in $4d/5d$ transition metal systems. A prime example is the $J_{\text{eff}}=\frac{1}{2}$ state in iridate materials and \RCL\ that drives Kitaev interactions. Here, by tuning the competition between spin-orbit interaction ($\lambda_{\text{SOC}}$) and trigonal crystal field splitting ($\Delta_\text{T}$), we restructure the spin-orbital wave functions into a novel $\mu=\frac{1}{2}$ state that drives Ising interactions. This is done via a topochemical reaction that converts \LRO\ to \ALRO, leading...

Vinod K. Sangwan, Joohoon Kang, David Lam, J. Tyler Gish, Spencer A. Wells, Jan Luxa, James P. Male, G. Jeffrey Snyder, Zdeněk Sofer & Mark C. Hersam
Emerging layered semiconductors present multiple advantages for optoelectronic technologies including high carrier mobilities, strong light-matter interactions, and tunable optical absorption and emission. Here, metal-semiconductor-metal avalanche photodiodes (APDs) are fabricated from Bi2O2Se crystals, which consist of electrostatically bound [Bi2O2]2+ and [Se]2− layers. The resulting APDs possess an intrinsic carrier multiplication factor up to 400 at 7 K with a responsivity gain exceeding 3,000 A/W and bandwidth of ~ 400 kHz at a visible wavelength of 515.6...

Accelerated Decomposition Kinetics of Ammonium Perchlorate via Conformal Graphene Coating

Michael D Garrison, Shay Goff Wallace, Lawrence C. Baldwin, Zixuan Guo, Lidia Kuo, Joseph E. Estevez, Alejandro L. Briseno, Mark C. Hersam & Alfred J. Baca
Ammonium perchlorate (AP) is an oxidizer material that is widely employed in applications ranging from rocketry to airbags. Previous research has suggested that efficient electron transfer plays a critical role in determining the kinetics of catalyzed AP decomposition reactions. Consequently, intimate contact between AP crystals and electron acceptors has the potential to accelerate decomposition kinetics, which motivates the development of conformal coatings with suitably tailored electronic structures. Here, we demonstrate a scalable method for conformally...

Datasets for Accelerating Catalysts Screening via Machine-learned Local Coordination Graph Representations

Hieu A. Doan, Chenyang Li, Logan Ward, Mingxia Zhou, Larry A. Curtiss & Rajeev S. Assary
A priori catalyst designs from reliable first principles simulations and emerging artificial intelligence tools are desired to accelerate materials development. In the context of upgrading biomass materials via deoxygenation reaction to value-added chemicals, molybdenum carbides (Mo2C) have been considered among the best and economically viable catalysts. One of the bottlenecks related to longer term stability of Mo2C catalysts is the susceptibility to surface oxidation, which requires the use of excess hydrogen for active site regeneration....
