Quantum wells and electron-hole systems are critical areas of research in condensed matter physics, particularly in the study of low-dimensional materials. These systems exhibit unique electronic ...

An international team of astronomers has detected mysterious chirping signals in an unexpected region of space, raising major ...

Because boron has one less electron than is required to form the bonds with the surrounding silicon atoms, an electron vacancy or “hole” is created. The n-type silicon is made by including atoms that ...
