In a new report on Science Advances, Chen Fang and Liang Fu from the Beijing National Laboratory for Condensed Matter Â鶹ÒùÔºics in China, Kavli Institute for Theoretical Sciences and the Department of Â鶹ÒùÔºics, Massachusetts ...
When a metal is heated to a sufficiently high temperature, electrons can be ejected out from the surface in a process known as the thermionic emission, a process that is similar to the evaporation of water molecules from ...
Transition metal dichalcogenides (TMDCs) formed by group 10 metals (e.g. PtSe2, PtTe2) have emerged as important materials with intriguing properties discovered both in bulk single crystals and atomically thin films. While ...
The search for better materials for computers and other electronic devices has focused on a group of materials known as "topological insulators" that have a special property of conducting electricity on the edge of their ...
Topological insulators are one of the most exciting discoveries of the 21st century. They can be simply described as materials that conduct electricity on their surface or edge, but are insulating in their interior bulk. ...
At the turn of the 20th century, scientists discovered that atoms were composed of smaller particles. They found that inside each atom, negatively charged electrons orbit a nucleus made of positively charged protons and neutral ...
A simple sheet of graphene has noteworthy properties due to a quantum phenomenon in its electron structure called Dirac cones. The system becomes even more interesting if it comprises two superimposed graphene sheets, and ...
The research focus on 2-D materials has intensified with its potential to modulate light for superior performance and realize applications that can enhance existing technologies. Graphene, the best known 2-D material, derived ...
A research team led by Pham Nam Hai at the Department of Electrical and Electronic Engineering, Tokyo Institute of Technology (Tokyo Tech) has developed the world's best-performing pure spin current source made of bismuth-antimony ...
The basic quanta of light (photon) and sound (phonon) are bosonic particles that largely obey similar rules and are in general very good analogs of one another. Â鶹ÒùÔºicists have explored this analogy in recent experimental ...
