Neutralizing Optical Defects in GeSn
Nirosh M. Eldose, Dinesh Baral, Diandian Zhang +7
Reports of photoluminescence from GeSn grown on Ge substrates by molecular beam epitaxy have been limited. We find that one limiting factor to observing photoluminescence is due to…

Correlations between Event Rates of Short Gamma-Ray Bursts and Star Formation Rates with/without Time Delay
X. Y. Du, Z. B. Zhang, W. C. Du +3
In this paper, we systematically investigate the redshift and luminosity distributions as well as the event rates of short Gamma-Ray Bursts (SGRBs) detected by Swift, Fermi, Konus-…
