Electronic noise of warm electrons in semiconductors from first-principles
Alexander Y. Choi, Peishi Cheng, Benjamin Hatanpaa +1
The ab-initio theory of low-field electronic transport properties such as carrier mobility in semiconductors is well-established. However, an equivalent treatment of electronic flu…
