Dirac fermion reflector by ballistic graphene sawtooth-shaped npn junctions
, 2017 We have realized a Dirac fermion reflector in graphene by controlling the ballistic carrier trajectory in a sawtooth-shaped npn junction. When the carrier density in the inner p-region is much larger than that in the outer n-regions, the first straight ...

Inherently Disordered Auxetic Metamaterials
Advanced Science, EarlyView.Inherently disordered auxetic metamaterials based on random chiral Delaunay triangulations are designed and investigated using numerical simulations and experimental tests. These disordered frameworks exhibit orthotropic behavior and a large negative Poisson's ratio (ca.

SOME FORENSIC ASPECTS OF BALLISTIC IMAGING [PDF]
, 2010 Analysis of ballistics evidence (spent cartridge casings and bullets) has been a staple of forensic criminal investigation for almost a century. Computer-assisted databases of images of ballistics evidence have been used since the mid-1980s to help ...

Thermally Modulated Specular Phonon Transport in a High‐Debye‐Temperature Diamond Nanobeam
Advanced Science, EarlyView.Thermal transport in single‐crystal diamond nanobeams is measured from 140 to 300 K using electro‐thermal micro‐suspended structures. The thermal conductivity shows an increasing deviation from Boltzmann transport predictions assuming fully diffuse boundary scattering at lower temperatures.

Light‐Harvesting Photothermal Hotspots Enabled by NIR Scattering‐Absorption Coupling
Advanced Science, EarlyView.By coupling the broadband scattering of nanodiamonds with the plasmonic absorption of gold nanostars, this work proposes a novel strategy for the active modulation of photon transport. This strategy creates localized photothermal hotspots in turbid media and achieves a supra‐additive heating efficiency, thereby providing a universal platform for low ...

Ballistic transport: A view from the quantum theory of motion
, 1994 Ballistic transport of electrons through a quantum wire with a constriction is studied in terms of Bohm's interpretation of quantum mechanics, in which the concept of a particle orbit is permitted.
