H2 Physisorbed on Graphane [PDF]
Journal of Low Temperature Physics, 2012 We study the zero-temperature phase diagrams of H2 adsorbed on the three structures predicted for graphane (chair, boat and washboard graphane), using a diffusion Monte Carlo technique. Graphane is the hydrogenated version of graphene, in which each carbon atom changes its hybridization to sp3 and forms a covalent bond with a hydrogen atom. Our results

Compression-Induced Dehydrogenation of Graphene: Insight from Simulations
Hydrogen, 2023 In this work, we reported the results of systematic studies of various configurations of chemically adsorbed hydrogen atoms on the surface of corrugated graphene induced by in-plane uniaxial compression. Different magnitudes of the substrate corrugations

Pump-Probe X-ray Photoemission Spectroscopy of Free-Standing Graphane
Condensed Matter, 2023 Free-standing nanoporous graphene was hydrogenated at about 60 at.% H uptake, as determined by the emerging of the sp3 bonding component in the C 1s core level investigated by high-resolution X-ray photoelectron spectroscopy (XPS).

Memristive, Spintronic, and 2D‐Materials‐Based Devices to Improve and Complement Computing Hardware
Advanced Intelligent Systems, Volume 4, Issue 8, August 2022., 2022 Moore's law has slowed down and, with the rise of data‐intensive applications, like machine learning, new approaches to computing hardware are needed. The perspective explores the role of memristive, spintronic, and 2D‐materials‐based devices in making conventional computers faster and more energy efficient, and in adopting new paradigms, like ...

Nuclear quantum effects in graphane [PDF]
Chemical Physics, 2020 Graphane is a quasi-two-dimensional material consisting of a single layer of fully hydrogenated graphene, with a C:H ratio of 1. We study nuclear quantum effects in the so-called chair-graphane by using path-integral molecular dynamics (PIMD) simulations.

Laser-induced preferential dehydrogenation of graphane [PDF]
Physical Review B, 2012 We have used first-principles simulations based on time-dependent density functional theory to show that short laser pulses can trigger preferential hydrogen desorption from the upper or lower side of suspended graphane (H-terminated graphene). This control is achieved by using intense ultrashort p-polarized laser pulses (∼2 fs) with an asymmetric time
