Diodes are widely used electronic devices that act as one-way switches for current. A well-known example is the LED (light-emitting diode), but there is a special class of diodes designed to make use of the phenomenon known ...
Interlayer excitons in transition metal dichalcogenides (TMDs) van der Waals (vdW) heterostructures exhibit fascinating physics and hold great promise for developing excitonic devices. Scientists in China present a systematical ...
High-performance micro-/nanostructure lasers, as multifunctional optical source components, are of great importance for optoelectronic devices. Towards this goal, scientists in China invented a high-efficiency ultrastable ...
The properties of carbon-based nanomaterials can be altered and engineered through the deliberate introduction of certain structural "imperfections" or defects. The challenge, however, is to control the number and type of ...
It may be possible in the future to use information technology where electron spin is used to store, process and transfer information in quantum computers. It has long been the goal of scientists to be able to use spin-based ...
A defect-free thin film of cuprous iodide—made up of just one crystal—has been fabricated by RIKEN physicists. The atomically flat sample is a boost for producing better semiconductors.
Multifunctional and diverse artificial neural systems can incorporate multimodal plasticity, memory and supervised learning functions to assist neuromorphic computation. In a new report, Jinran Yu and a research team in nanoenergy, ...
Two-dimensional (2D) perovskites are multiple quantum well (QW) structures formed by alternating inorganic and organic layers. They are promising in applications of solar cells, LEDs, and photodetectors.
Analytical chemistry aims to efficiently discriminate between two amino acids. In a new report in Science Advances, Zihao Liu and a research team in Chemistry, Â鶹ÒùÔºics, and Materials Science in China and Japan, used a single-molecule ...
KAIST researchers and their collaborators at home and abroad have successfully demonstrated a new methodology for direct near-field optical imaging of acoustic graphene plasmon fields. This strategy will provide a breakthrough ...
