Reevaluating the electrical impact of atomic carbon impurities in MoS2
James Ramsey, Faiza Alhamed, Jonathan P. Goss +2
Transition metal dichalcogenides, a family of two-dimensional compounds, are of interest for a range of technological applications. MoS2, the most researched member of this family,…
Doubly-charged silicon vacancy center, photochromism, and Si-N complexes in co-doped diamond
B G Breeze, C J Meara, X X Wu +13
We report the first experimental observation of a doubly-charged defect in diamond, SiV2-, in silicon and nitrogen co-doped samples. We measure spectroscopic signatures we attribut…
Density functional theory study of substitutional oxygen in diamond
K. M. Etmimi, P. R. Briddon, A. M. Abutruma +2
A few studies have been recently presented for the existence of oxygen in diamond, for example, the N3 EPR centres have been theoretically and experimentally assigned the model mad…
Electronic structure modification of Si-nanocrystals with F4 -TCNQ
A. Carvalho, J. Coutinho, M. Barroso +4
We use first-principles models to demonstrate how an organic oxidizing agent, F4 -TCNQ (7,7,8,8- tetracyano-2,3,5,6-tetrafluoroquinodimethane), modifies the electronic structure of…
Stable hydrogenated graphene edge types: Normal and reconstructed Klein edges
Philipp Wagner, Viktoria V. Ivanovskaya, Manuel Melle-Franco +4
Hydrogenated graphene edges are assumed to be either armchair, zigzag or a combination of the two. We show that the zigzag is not the most stable fully hydrogenated structure along…
Mechanical properties of nanosheets and nanotubes investigated using a new geometry independent volume definition
Philipp Wagner, Viktoria V. Ivanovskaya, Mark J. Rayson +2
Cross-sectional area and volume become difficult to define as material dimensions approach the atomic scale. This limits the transferability of macroscopic concepts such as Young's…
