Relativistic stable processes in quasi-ballistic heat conduction in thin film semiconductors
Prakash Chakraborty, Bjorn Vermeersch, Ali Shakouri +1
In this article, we show how relativistic alpha stable processes can be used to explain quasi-ballistic heat conduction in semiconductors. This is a method that can fit experimenta…
Thermal resistance of GaN/AlN graded interfaces
Ambroise van Roekeghem, Bjorn Vermeersch, Jesús Carrete +1
Compositionally graded interfaces in power electronic devices eliminate dislocations, but they can also decrease thermal conduction, leading to overheating. We quantify the thermal…
Closed periodic orbits in anomalous gravitation
Bjorn A. Vermeersch
Newton famously showed that a gravitational force inversely proportional to the square of the distance, , formally explains Kepler's three laws of planetary motion. B…
Predictive design and experimental realization of InAs/GaAs superlattices with tailored thermal conductivity
J. Carrete, B. Vermeersch, L. Thumfart +7
We demonstrate an ab-initio predictive approach to computing the thermal conductivity () of InAs/GaAs superlattices (SLs) of varying period, thickness, and composition. Our new…
Quasiballistic heat removal from small sources studied from first principles
Bjorn Vermeersch, Natalio Mingo
Heat sources whose characteristic dimension is comparable to phonon mean free paths display thermal resistances that exceed conventional diffusive predictions. This has direct…
almaBTE: a solver of the space-time dependent Boltzmann transport equation for phonons in structured materials
Jesús Carrete, Bjorn Vermeersch, Ankita Katre +4
almaBTE is a software package that solves the space- and time-dependent Boltzmann transport equation for phonons, using only ab-initio calculated quantities as inputs. The program…
