Revisiting the barometric equation and the extent of a planetary atmosphere
Marcos Grimsditch, Victor G. Karpov
The barometric equation predicts the molecular concentration exponentially decaying with altitude . Because the mean free path increases exponentially, at high a…
Metal whisker growth induced by localized, high-intensity DC electric fields
Vamsi Borra, Osama Oudat, Daniel G. Georgiev +2
In this work, a very high, locally applied electric field was used to induce whisker nucleation on an Sn film. The field was generated by using a conductive AFM tip and applying a…
Cultivating Metal Whiskers by Surface Plasmon Polariton Excitation
Vamsi Borra, Daniel G. Georgiev, Victor G. Karpov
This work presents a preliminary experimental study on the possibility to initiate growth of whiskers on the surfaces of some technologically important metals utilizing the enhance…
Modification of Tin (Sn) Metal Surfaces by Surface Plasmon Polariton Excitation
Vamsi Borra, Srikanth Itapu, Victor G. Karpov +1
We report on the modification of tin (Sn) film surfaces under a laser beam irradiation that triggers surface plasmon polariton (SPP) excitations. The observed surface features in t…
Threshold Switching in CdTe Photovoltaics
Suman Devkota, Kwame A Nyako, Brendan Kuzior +5
With the ubiquitous acceptance of PVs, the number of devices manufactured annually is following an exponential trend. Yet, the manufacturing process of important brands of thin fil…
Voltage deficit in solar cells with suppressed recombination
Victor Karpov, Diana Shvydka
The observed open circuit voltages in best performing solar cells are explained outside of the recombination paradigm, based on such factors as electrostatic screening, Meyer-Nelde…
