Carrier generation and recombinationIn the solid-state physics of semiconductors, carrier generation and carrier recombination are processes by which mobile charge carriers (electrons and electron holes) are created and eliminated. Carrier generation and recombination processes are fundamental to the operation of many optoelectronic semiconductor devices, such as photodiodes, light-emitting diodes and laser diodes. They are also critical to a full analysis of p-n junction devices such as bipolar junction transistors and p-n junction diodes.
Densité d'états électroniquesEn physique du solide et physique de la matière condensée, la densité d'états électroniques, en anglais Density of States ou DOS, quantifie le nombre d'états électroniques susceptibles d’être occupés, et possédant une énergie donnée dans le matériau considéré. Elle est généralement notée par l'une des lettres g, ρ, D, n ou N. Plus précisément, on définit la densité d'états par le fait que est le nombre d'états électroniques disponibles, avec une énergie comprise entre et , par unité de volume du solide ou par maille élémentaire du cristal étudié.
Course of Theoretical PhysicsThe Course of Theoretical Physics is a ten-volume series of books covering theoretical physics that was initiated by Lev Landau and written in collaboration with his student Evgeny Lifshitz starting in the late 1930s. It is said that Landau composed much of the series in his head while in an NKVD prison in 1938–1939. However, almost all of the actual writing of the early volumes was done by Lifshitz, giving rise to the witticism, "not a word of Landau and not a thought of Lifshitz".
