Improving low-loss dielectric measurement technique

Scientists from NPL have developed improvements to a technique for measuring dielectric permittivity and loss of materials at MHz frequencies. The method used is named after two NPL scientists who developed in the 1930, Hartshorn ...

Insulators turn up the heat on quantum bits

Physicists have long suspected that dielectric materials may significantly disrupt ion-trap quantum computers. Now, researchers led by Tracy Northup have developed a new method to quantify this source of error for the first ...

Smart dielectric elastomers for self-healing soft robots

Robots that resemble organs are known as soft robots, and in order for them to function they must be made of a flexible material, however a material that can also heal itself would be a bonus if wear and tear was to occur. ...

Finding high-Q resonant modes in a dielectric nanocavity

Optical resonators provide the foundation of modern photonics and optics. Thanks to its extreme energy confinement, the high-Q-factor optical resonator optimizes light-matter interaction and photonic device performance by ...

Alcohols exhibit quantum effects

Skoltech scientists and their colleagues from the Russian Quantum Center revealed a significant role of nuclear quantum effects in the polarization of alcohol in an external electric field. Their research findings are published ...

Researchers invent broad-band tunable terahertz absorber

Recently, a research team led by Prof. SHENG Zhigao from the High Magnetic Field Laboratory of the Hefei Institutes of Physical Science (HFIPS), along with collaborators in HFIPS and ShanghaiTech University, invented a broad-band ...

The new composite prevents malfunctions of electronic devices

Scientists from South Ural State University, in collaboration with colleagues from Belarus, India and China, have created a composite material for nanoelectronics. The material can be used as a dielectric (insulating substance) ...
