Chemical Bonding in Chalcogenides
The precise nature of chemical-bonding interactions in amorphous, and crystalline, chalcogenides is still unclear due to the complexity arising from the delocalization of bonding, and nonbonding, electrons. Although an...
Hypervalency in amorphous chalcogenides
The concept of hypervalency emerged as a notion for chemical bonding in molecules to explain the atomic coordination in hypervalent molecules that violates the electron-octet rule. Despite its significance, however, hypervalency...
Revealing the intrinsic nature of the mid-gap defects in amorphous Ge 2 Sb 2 Te 5
Abstract: Understanding the relation between the time-dependent resistance drift in the amorphous state of phase-change materials and the localised states in the band gap of the glass is crucial for the development of memory...
Revealing the intrinsic nature of the mid-gap defects in amorphous Ge2Sb2Te5.
Understanding the relation between the time-dependent resistance drift in the amorphous state of phase-change materials and the localised states in the band gap of the glass is crucial for the development of memory devices with...
Origin of radiation tolerance in amorphous Ge2Sb2Te5 phase-change random-access memory material.
The radiation hardness of amorphous Ge2Sb2Te5 phase-change random-access memory material has been elucidated by ab initio molecular-dynamics simulations. Ionizing radiation events have been modeled to investigate their effect on...
Gaussian approximation potential modeling of lithium intercalation in carbon nanostructures.
So Fujikake, Volker L Deringer, Tae Hoon Lee, Marcin Krynski, Stephen R Elliott, Gábor Csányi
Feb 27, 2018
We demonstrate how machine-learning based interatomic potentials can be used to model guest atoms in host structures. Specifically, we generate Gaussian approximation potential (GAP) models for the interaction of lithium atoms...

Toward Single-Cell Multiple-Strategy Processing Shift Register Powered by Phase-Change Memory Materials
Modern innovations are built on the foundation of computers. Compared to von Neumann architectures having separate storage and processing units, in‐memory operation utilizes the same primary structure for data storage and...
Highly Efficient Light-Emitting Diodes of Colloidal Metal-Halide Perovskite Nanocrystals beyond Quantum Size.
Young-Hoon Kim, Christoph Wolf, Young-Tae Kim, Himchan Cho, Woosung Kwon, Sungan Do, Aditya Sadhanala, Chan Gyung Park, Shi-Woo Rhee, Sang Hyuk Im, Richard H Friend, Tae-Woo Lee
Nov 24, 2017
Colloidal metal-halide perovskite quantum dots (QDs) with a dimension less than the exciton Bohr diameter DB (quantum size regime) emerged as promising light emitters due to their spectrally narrow light, facile color tuning...
Towards an atomistic understanding of disordered carbon electrode materials.
Volker L Deringer, Céline Merlet, Yuchen Hu, Tae Hoon Lee, John A Kattirtzi, Oliver Pecher, Gábor Csányi, Stephen R Elliott, Clare P Grey
Aug 15, 2018
Disordered nanoporous and "hard" carbons are widely used in batteries and supercapacitors, but their atomic structures are poorly determined. Here, we combine machine learning and DFT to obtain new atomistic insight into...
