Robust interpretation of electrochemical impedance spectra using numerical complex analysis
Jithin D. George, Willa Brenneis, Vinod K. Sangwan +9
Electrochemical Impedance Spectroscopy (EIS) is a non-invasive technique widely used for understanding charge transfer and charge transport processes in electrochemical systems and…
All-antiferromagnetic electrically controlled memory on silicon featuring large tunneling magnetoresistance
Jiacheng Shi, Victor Lopez-Dominguez, Sevdenur Arpaci +14
Antiferromagnetic (AFM) materials are a pathway to spintronic memory and computing devices with unprecedented speed, energy efficiency, and bit density. Realizing this potential re…
Low Frequency Carrier Kinetics in Perovskite Solar Cells
Vinod K. Sangwan, Menghua Zhu, Sarah Clark +4
Hybrid organic-inorganic halide perovskite solar cells have emerged as leading candidates for third-generation photovoltaic technology. Despite the rapid improvement in power conve…
Self-Assembled Photochromic Molecular Dipoles for High Performance Polymer Thin-Film Transistors
Satyaprasad P. Senanayak, Vinod K. Sangwan, Julian J. McMorrow +6
The development of high-performance multifunctional polymer-based electronic circuits is a major step towards future flexible electronics. Here, we demonstrate a tunable approach t…
Charge Separation at Mixed-Dimensional Single and Multilayer MoS2/Silicon Nanowire Heterojunctions
Alex Henning, Vinod K. Sangwan, Hadallia Bergeron +4
Layered two-dimensional (2-D) semiconductors can be combined with other low-dimensional semiconductors to form non-planar mixed-dimensional van der Waals (vdW) heterojunctions whos…
Gate-tunable memristors from monolayer MoS2
Vinod K. Sangwan, Hong-Sub Lee, Mark C. Hersam
We report here gate-tunable memristors based on monolayer MoS2 grown by chemical vapor deposition (CVD). These memristors are fabricated in a field-effect geometry with the channel…
