Excitons are electron-hole pairs in semiconductors that are electrostatically bound by strong Coulombic interactions. In ultrathin 2D semiconductors that are a few atoms thick (typically ~0.7 nm ...

A Hubble image of the galaxy MCG-03-34-064 reveals three bright dots at the galaxy's center two of which are X-ray blasting black holes. (Image credit: NASA, ESA, Anna Trindade Falcão (CfA ...

Physics & Chemistry Physicists Capture First-Ever Image of an Electron Crystal The findings affirm a 90-year-old theory about how electrons can assemble without atoms.

Electron Vs. Hole Movement: When an external voltage is applied to a semiconductor, it creates an electric field. This electric field pushes electrons in one direction (conventional current flow).

This is the second polarized light image of a black hole from EHT. The first was of M87*, a supermassive black hole that blasts out a massive jet from galaxy Messier 87 and which starred in EHT ...

The EHT collaboration finally announced the first image of SgrA* in 2022, showing that it has a ring structure. But astronomers still didn't know how the Milky Way's supermassive black hole is ...

Astronomers found interesting insights into the heaviest black hole pair ever found. By Jace Dela Cruz Updated: Mar 01 2024, 06:05 AM EST ...

The team estimates the binary’s mass to be a whopping 28 billion times that of the Sun, qualifying the pair as the heaviest black hole binary ever measured.

Both sides now: artist's impression of bilayer graphene with an electron-hole symmetric double quantum dot, where the electron and the hole are in different layers. (Courtesy: Sebastian Staacks) ...
