Chemical trends of deep levels in van der Waals semiconductors
Penghong Ci, Xuezeng Tian, Jun Kang +11
Properties of semiconductors are largely defined by crystal imperfections including native defects. Van der Waals (vdW) semiconductors, a newly emerged class of materials, are no e…
Bistable Amphoteric Native Defect Model of Perovskite Photovoltaics
W. Walukiewicz, I. Rey-Stolle, G. Han +6
The past few years have witnessed unprecedented rapid improvement of the performance of a new class of photovoltaics based on halide perovskites. This progress has been achieved ev…
THz Transient Photoconductivity of the III-V Dilute Nitride GaPAsN
J. N. Heyman, E. M. Weiss, J. R. Rollag +5
THz Time-Resolved Photoconductivity is used to probe carrier dynamics in the dilute III-V nitride GaP0.49As0.47N0.036. In these measurements a femtosecond optical pump-pulse excite…
Carrier Lifetimes in a III-V-N Intermediate Band Semiconductor
J. N. Heyman, A. M. Schwartzberg, K. M. Yu +5
We have used transient absorption spectroscopy to measure carrier lifetimes in the multiband band semiconductor GaPAsN. These measurements probe the electron populations in the con…
Response to the comment of K.W. Edmonds et al. on the article 'Controlling the Curie temperature in (Ga,Mn)As through location of the Fermi level within the impurity band'
M. Dobrowolska, X. Liu, J. K. Furdyna +3
Although we seriously disagree with many of the points raised in the comment by Edmonds et al., we feel that it is valuable and timely, since comparison of this comment and our pap…
Controlling Curie temperature in (Ga,Ms)As through location of the Fermi level within the impurity band
M. Dobrowolska, K. Tivakornsasithorn, X. Liu +4
The ferromagnetic semiconductor (Ga,Mn)As has emerged as the most studied material for prototype applications in semiconductor spintronics. Because ferromagnetism in (Ga,Mn)As is h…
