Microscopic electric fields govern a remarkable variety of phenomena in condensed matter and their ultrafast evolutions drive plasmonics, phononics and highspeed nanoelectronics. Access to high-frequency electric waveforms is of crucial importance to diverse disciplines in nanoscience and technology, yet, microscopic measurements are still severely limited.
An international team of scientists may have solved a key mystery about the origins of the Earth’s water, after uncovering persuasive new evidence pointing to an unlikely culprit - the Sun.
A two-dimensional (2D) nanomaterial-based flexible memory device is a critical element in the next-generation wearable market because it plays a crucial role in data storage, processing, and communication.
Graphene consists of a planar structure, with carbon atoms connected in a hexagonal shape that resembles a beehive. When graphene is reduced to several nanometers (nm) in size, it becomes a graphene quantum dot that exhibits fluorescent and semiconductor properties.
If spilled coffee is not immediately wiped off, it leaves behind a stain where the edges are darker than the rest. This phenomenon is called the coffee ring effect.
Quantum dots, discovered in the 1990s, have a wide range of applications and are perhaps best known for producing vivid colors in some high-end televisions.
Information storage and transfer in the manner of simple ones and zeros-;as in today's classical computer technologies-;is insufficient for quantum technologies under development.
Convolutional neural networks running on quantum computers have generated significant buzz for their potential to analyze quantum data better than classical computers can.
At the Institute of Scientific and Industrial Research (SANKEN) of Osaka University, scientists have trained a deep neural network to accurately identify the output state of quantum bits, even in the presence of environmental noise.
Using organic DAST crystals pumped with mid-IR pulses, researchers have created an exceptionally strong terahertz field that can directly drive a large change in transmission of a visible probe pulse in quantum dots.
