Representation aiding (and similar approaches that share the general orientation) has a great deal of utility, predictive ability, and explanatory power. Marino and Mahan (2005) discuss principles that are critical to the RA approach (configurality, emergent features, and mappings) in a reasonable fashion. However, the application of these principles is far from reasonable. The authors explicit...

Thermoelectric phenomena in photoexcited graphene have been the topic of several theoretical and experimental studies because their potential usefulness optoelectronic applications. However, available descriptions thermoelectric effect terms Seebeck coefficient do not take into account role electron density. In this work, we adopt concept effective [G.D. Mahan, J. Appl. Phys. 87, 7326 (2000)] e...
