TL;DR: Two-dimensional C Kα RIXS mapping of the heavy reduction of rGOs further confirms that the residual oxygen and/or oxygen-containing functional groups modify the π and σ features, which are dispersed by the photon excitation energy.

TL;DR: These findings corroborate well with the first-principles calculations of C-implanted ZnO in surface and bulk regions, which highlight the stability of implanted C for the suppression and enhancement of the ferromagnetism of theZnO-C:NW in the surface region and bulk phase, respectively.

Y. F. Wang,Shashi B. Singh,Shashi B. Singh,Mukta V. Limaye,Mukta V. Limaye,Y. C. Shao,S. H. Hsieh,L. Y. Chen,H. C. Hsueh,H. T. Wang,J. W. Chiou,Yu-Chang Yeh,C. W. Chen,C. H. Chen,Sekhar C. Ray,Jianxin Wang,W. F. Pong,Yasumasa Takagi,Takuji Ohigashi,Toshihiko Yokoyama,Nobuhiro Kosugi +20 more
TL;DR: The results of X-ray magnetic circular dichroism further support the finding that C 2p(σ*)-derived states are the main origin of the magnetism of GO.
Understanding of sub-band gap absorption of femtosecond-laser sulfur hyperdoped silicon using synchrotron-based techniques
Mukta V. Limaye,S. C. Chen,C. Y. Lee,L. Y. Chen,Shashi B. Singh,Shashi B. Singh,Y. C. Shao,Y. F. Wang,S. H. Hsieh,H. C. Hsueh,J. W. Chiou,C. H. Chen,L. Y. Jang,Chia-Liang Cheng,W. F. Pong,Yongfeng Hu +15 more
TL;DR: The chemical state of theS species and the formation of the S-dopant states in the band gap of Si are critical in determining the sub-band gap absorptance of hyperdoped Si samples.
Defect induced room temperature ferromagnetism in single crystal, poly-crystal, and nanorod ZnO: A comparative study
B. Ghosh,Sekhar C. Ray,Mbule Pontsho,Sweety Sarma,Dilip Kumar Mishra,Y. F. Wang,W. F. Pong,André M. Strydom +7 more
TL;DR: In this article, a comparative study has been made for the defect induced room temperature ferromagnetism of single crystal, poly-crystal, and nanorod zinc oxide (ZnO) based on the magnetic properties and electronic properties by means of X-ray absorption near edge structure spectroscopy (XANES), X -ray photoelectron spectroglobalization, ultraviolet photo electrophoresis (UPS), valence band photoemission spectromission (VB-PES), and SQUID-type magnetometry.
