Fermi-level mediated acceleration of flash sintering of oxide ceramics
Qin-Kun Li, Evgeni S. Penev, Boris I. Yakobson
The atomistic understanding of flash sintering (FS) remains speculative, despite its efficiency and versatility in materials processing. Employing first-principles calculations we…
Stability and electronic properties of two-dimensional gallium
Alex Kutana, Qiyuan Ruan, Jun-Jie Zhang +2
Two-dimensional metals offer intriguing possibilities to explore metallicity and other related properties in systems with reduced dimensionality. Here, following recent experimenta…
Elasticity, Flexibility and Ideal Strength of Borophenes
Zhuhua Zhang, Yang Yang, Evgeni S. Penev +1
We study the mechanical properties of two-dimensional (2D) boron, borophenes, by first-principles calculations. The recently synthesized borophene with 1/6 concentration of hollow…
Why do nanotubes grow chiral?
Vasilii I. Artyukhov, Evgeni S. Penev, Boris I. Yakobson
Carbon nanotubes (CNT) hold enormous technological promise. It can only be harnessed if one controls in a practical way the CNT chirality, the feature of the tubular carbon topolog…
Effect of strain on surface diffusion in semiconductor heteroepitaxy
Evgeni Penev, Peter Kratzer, Matthias Scheffler
We present a first-principles analysis of the strain renormalization of the cation diffusivity on the GaAs(001) surface. For the example of In/GaAs(001)-c(4x4) it is shown that the…
First-principles studies of kinetics in epitaxial growth of III-V semiconductors
P. Kratzer, E. Penev, M. Scheffler
We demonstrate how first-principles calculations using density-functional theory (DFT) can be applied to gain insight into the molecular processes that rule the physics of material…
