Superfluidity of Grain Boundaries in Solid 4He
Quantum monte carlo simulation crystal cryogenic superfluid super fluid particles
2014/12/20
By large-scale quantum Monte Carlo simulations we show that grain boundaries in 4He crystals are generically superfluid at low temperature, with a transition temperature of the order of ～0.5 ...
Single-crystal Grains and Grain Boundaries in Graphene Grown by Chemical Vapor Deposition
Single-crystal Grains Grain Boundaries Chemical Vapor Deposition
2010/11/25
Graphene has attracted enormous attention due to its numerous remarkable properties and wide range of potential applications. To fully realize its potential, graphene needs to be synthesized in large ...
Spectral Properties of Grain Boundaries at Small Angles of Rotation
Schr¨odinger operators eigenvalues spectral gaps
2010/12/9
We study some spectral properties of a simple two-dimensional model for small angle defects in crystals and alloys. Starting from a periodic potential V : R2 → R, we let V#(x, y) = V (x, y) in the rig...

Structure and formation mechanism of low-angle grain boundaries in chlorite
Structure formation mechanism low-angle grain boundaries
2012/3/31
The structure and formation mechanisms of low-angle grain boundaries (LAGB) in chlorite have been investigated using HRTEM to resolve each cation sheet in chlorite. The LAGB are abundant in two hydrot...
