Covalent Bonding: Concept of electronegativity, Fajan’s rule, dipole moment, Valence Shell Electron Pair Repulsion (VSEPR ) theory and shapes of simple molecules. Quantum mechanical approach to ...

However, materials like diamond, often used in electronic components, have a much larger energy gap between their valence and conduction bands—typically exceeding 4 electron volts (eV)—making ...

N-type semiconductors use dopant atoms from elements in group V, with five or more electrons in their valence shell. Readily available phosphorus is a common choice. The "spare" electron from each ...

“Although a wide range of [superconductor] correlated phenomena have indeed been observed in the moiré TMDs, robust ...

Researchers have been working for decades to understand the architecture of the subatomic world. One of the knottier questions has been where the proton gets its intrinsic angular momentum, otherwise ...

Protons are far from simple particles — they are swirling cauldrons of quarks, gluons, and quantum entanglement. Scientists ...

Recently, the work was completed by the group of Prof. Sheng Meng from the Institute of Physics, Chinese Academy of Sciences, and Beijing National Research Center for Condensed Matter Physics. By ...

In recent years, there have been attempts to describe the inside of a proton using quantum information tools, with partial ...

are directly aligned with the conduction band (the electron shell adjacent to the valence band). The direct band gap in tungsten diselenide allows for electrons to easily transition from the ...
