Phonons are collective atomic vibrations, or quasiparticles, that act as the main heat carriers in a crystal lattice. Under certain circumstances, their properties can be modified by electric fields or light. But until now, ...
In a closed physical system, the sum of all angular momentum remains constant, according to an important physical law of conservation. Angular momentum does not necessarily need to involve "real" bodily rotation in this context: ...
A study published in Advanced Materials reveals the thermal transport properties of ultrathin crystals of molybdenum diselenide, a two-dimensional material of the transition metal dichalcogenide (TMD) family. Outperforming ...
Researchers have known about high-temperature superconducting copper-based materials, or cuprates, since the 1980s. Below a certain temperature (approximately -130 degree Celsius), electrical resistance vanishes from these ...
Vanderbilt researchers Sokrates Pantelides and Joshua Caldwell are part of an international collaboration that has demonstrated a new way to manipulate and measure subtle atomic vibrations in nanomaterials. This breakthrough ...
FeSe, an iron-based superconductor, is an important prototype material to study the superconduction-related properties, and electron-phonon coupling (EPC) plays an important role in FeSe. Pressure changes the structure of ...
In the particle world, sometimes two is better than one. Take, for instance, electron pairs. When two electrons are bound together, they can glide through a material without friction, giving the material special superconducting ...
It is one of the humans' desired goals that we want to precisely control the heat transport as the level as that we can control the electrical current. However, a high-performance thermal rectifier or thermal diode is still ...
In a new publication from Opto-Electronic Advances, the research groups of Professor Zhong-Qun Tian from Xiamen University, Xiamen, China and Professor Huigao Duan from Hunan University Changsha, China discuss nanobridged ...
Topological materials move electrons along their surface and edges without any loss, making them promising materials for dissipationless, high-efficiency electronics. Researchers are especially interested in using these materials ...
