WebMar 31, 2024 · In an emission process, a photon is emitted. Einstein found that the emission of a photon is possible by two different processes, spontaneous and stimulated emission, and that the coefficients describing the three processes—absorption, stimulated and spontaneous emission—are related to each other (Einstein relations). WebAug 5, 2011 · We use the Einstein relation qD/µ = k B T , although its validity for organic semiconductors can be questioned [42, 43,44]. In order to solve these coupled non-linear equations for the 2D ...
WebSep 7, 2024 · Density of States. The Debye model is a method developed by Peter Debye in 1912 [ 7] for estimating the phonon contribution to the specific heat (heat capacity) in a solid [ 1]. This model correctly explains the low temperature dependence of the heat capacity, which is proportional to T3 and also recovers the Dulong-Petit law at high temperatures. WebOct 26, 2015 · In Sect. 3 we derive analytical expressions for the two-term approximation for the case of the hard sphere model (also called the rigid sphere model) and obtain the Generalized Einstein relations. In Sect. 4 we explore if the Langevin equation can be used to obtain the results of Sect. 3 in order to support its use, when Einstein quotient is ...
