The ‘Generalized Skettrup Model’ and Specific Lattice Thermal Capacity of Non-Homogeneous and Low-Dimensional Semiconductors and Insulators

Authors: Valeri LIGATCHEV
Comments: 21 Pages. This paper is devoted to an extended discussion on some new aspects of the ‘Generalized Skettrup Model’ (GSM) described in details in the second chapter of my book ‘Polycrystalline and Spatially Non-Homogeneous Amorphous Semiconductors’ published in 2017.

The ‘Generalized Skettrup Model’ (GSM) links features of near-band gap and intra-gap electronic as well as corresponding optical spectra of polycrystalline and spatially non-homogeneous amorphous semiconductors and insulators to probabili-ties of equilibrium fluctuations in an energy of the individual quasi-particle, number of quasi-particles in a quantum grand canonical ensemble of confined acoustic phonons with static plane-wave basis (pure states), and in their aggregate energy. The essentially many-body GSM might be implemented as well at evaluations on harmonic and anharmonic contributions to the specific lattice thermal capacity of those semiconductors and insulators, as well as their low-dimensional counterparts. Herein predictions of the ‘refined’ GSM equations in these areas are compared with appropriate experimental results and outcomes of canonical Debye – Planck model.

Hot Spots vs. Green House Gases - Contribution to Global Warming – New Theory and Index

Authors: Alec Feinberg
Comments: 5 Pages.

In this paper we provide a simple thermodynamic proof that manmade Hot Spot heat generation would also create global warming even if CO2 emissions were at normal levels. We introduce the concept of global warming industrial revolution equilibrium heat index to establish this proof. We define manmade hot spot emission as unnatural heat emission produced by man that would not have occurred prior to the industrial revolution. The CO2 theory of global warming, while central to the issue as a huge part of the problem, has created a diversion to this other likely major contributor, namely hot spots contribution to global warming. It is obvious that there is a major focus on CO2 emissions and absolutely no focus on hot spot reduction in terms of solving the global warming crisis. This paper will hopefully provide motivation for the mitigation of hot spot creation. Knowledge of the root causes of the global warming problem is important to addressing the problem properly.
