• Visualization and Manipulation of Bilayer Graphene Quantum Dots with Broken Rotational Symmetry and Nontrivial Topology

  Nano Letters · 2020 · 33 citations

  Electrostatically defined quantum dots (QDs) in Bernal stacked bilayer graphene (BLG) are a promising quantum information platform because of their long spin decoherence times, high sample quality, and tunability. Importantly, the shape of QD states determines the electron energy spectrum, the interactions between electrons, and the coupling of electrons to their environment, all of which are relevant for quantum information processing. Despite its importance, the shape of BLG QD states remains…

• Ionic liquid multistate resistive switching characteristics in two terminal soft and flexible discrete channels for neuromorphic computing

  Microsystems & Nanoengineering · 2022 · 30 citations

  O into the two ends of a discrete polydimethylsiloxane (PDMS) channel. The spike rate-dependent plasticity (SRDP) and spike-timing-dependent plasticity (STDP) behavior are highly stable by modulating the input signal. Furthermore, the discrete channel device presents highly durable performance under mechanical bending and stretching. Using the obtained parameters from the proposed ionic liquid-based synaptic device, convolutional neural network simulation runs to an image recognition task, reach…

• Asymmetric GaN/ZnO Engineered Resistive Memory Device for Electronic Synapses

  ACS Applied Electronic Materials · 2022 · 25 citations

  The asymmetric resistive memory device can be more suitable to reduce the crosstalk effect in a crossbar array. Similarly, this work focused on the material and design concept to achieve a one-directional engineered resistive switching memory device to reduce crosstalk effect for electronic synapses. The pulsed modulated DC sputtered crystalline GaN heterojunction with ITO/ZnO Schottky diode, resulting in one-directional digital resistive switching. The DC sputtered polycrystalline GaN is used o…

• Seawater electrolysis at ultra-high current density: A comparative analysis of cylindrical versus conical electrodes

  International Journal of Hydrogen Energy · 2025-03-01 · 3 citations

  articleOpen accessSenior authorCorresponding

  Seawater electrolysis preferentially leans towards Chlorine Evolution Reaction (CER) over Oxygen Evolution Reactions (OER) under conventional conditions, but OER becomes more dominant at sufficiently higher current densities. In this study, we evaluated the effector of cylindrical and conical electrode geometries on CER and hydrogen production at high current density (i.e., >1 A cm −2 ). We found the point of lowest CER within a voltage range of 40 V–90 V. Conical electrodes, optimized to reduce…
