TL;DR: In this paper, a comparative study of ultrafast photoexcited state relaxation in pentacene single crystals and in pure and C60-doped Pentacene films using optical pump-probe spectroscopy is presented.
Journal ArticleDOI
Single-layer terahertz metamaterials with bulk optical constants
Wen-Chen Chen,Atcha Totachawattana,Kebin Fan,Joseph Ponsetto,Andrew C. Strikwerda,Xin Zhang,Richard D. Averitt,Willie J. Padilla +7 more
TL;DR: In this article, the conditions under which single layer metamaterials may be described by bulk optical constants were investigated, and guidelines for when ε-ensuremath{\epsilon}$ and ε -ensuresuremath{mu}$ can be used as material parameters for single-layer metammaterials.
Journal ArticleDOI
Ultrafast carrier dynamics in an InAs/InGaAs quantum dots-in-a-well heterostructure
Rohit P. Prasankumar,R. S. Attaluri,Richard D. Averitt,Junji Urayama,N. R. Weisse-Bernstein,P. Rotella,Andreas Stintz,Sanjay Krishna,A. J. Taylor +8 more
TL;DR: It is found that carrier capture and relaxation are dominated by Auger carrier-carrier scattering at low temperatures, with thermal emission playing an increasing role with temperature.
Journal ArticleDOI
Quasiparticle relaxation across the spin-density-wave gap in the itinerant antiferromagnet U Ni Ga 5
Elbert E. M. Chia,Jian-Xin Zhu,H. J. Lee,Namjung Hur,N. O. Moreno,Eve Bauer,Tomasz Durakiewicz,Richard D. Averitt,J. L. Sarrao,A. J. Taylor +9 more
TL;DR: In this article, the authors measured photo-induced reflectivity for the itinerant antiferromagnet and showed that the relaxation time of the Antiferromagnetic Network exhibits a sharp increase with the opening of a spin-density-wave (SDW) gap.
