Field-Driven Hybrid Filament Formation Governs Switching in Ta-HfO-Pt Memristors
Ashutosh Krishna Amaram, Aditya Koneru, Subramanian KRS Sankaranarayanan
Memristive devices have gained significant attention for their potential in next-generation non-volatile memory and neuromorphic computing architectures. Among emerging candidates,…
Harnessing Structural Disorder: Unraveling Hydrogen Evolution in Monolayer Amorphous Carbon via First-Principles Simulations and Machine-Learned Potentials
Sreehari M S, Ashutosh Krishna Amaram, Raghavan Ranganathan
Disorder and defective coordination in the catalytic plane are crucial for enhancing the Hydrogen Evolution Reaction (HER) on two-dimensional catalysts. Amorphous materials are dis…
Investigation of resistive switching in Au/MoS2/Au using Reactive Molecular Dynamics and ab-initio quantum transport calculations
Ashutosh Krishna Amaram, Saurabh Kharwar, Tarun Kumar Agarwal
In this work, we investigate the underlying physical mechanism for electric-field induced resistive switching in Au/MoS2/Au based memristive devices by combining reactive Molecular…
A First-Principles Investigation of Goldene for Enhanced Hydrogen Evolution Reaction
Ashutosh Krishna Amaram, Aaditya Roy, Raghavan Ranganathan
The recent synthesis of Goldene, a 2D sheet of gold exfoliated from , offers high specific surface area (~260 ), roughly twice that of fine nanodots (~100 $m^…
