Energy Transport in Bi-Te-Se Topological Insulators
Presentation Materials | 21 Mar 2019 | Contributor(s): Shouyuan Huang, Vasudevan Iyer, Xianfan Xu
Topological insulators (TIs) are a new phase of material that allows metallic conducting electrons at its surface while the bulk is insulating. Besides, the topological surface electrons’ spin orientation is always locked perpendicular to its moving direction, called...
Nanoscale Antenna Apertures
0.0 out of 5 stars
Online Presentations | 24 Apr 2007 | Contributor(s): Xianfan Xu
This presentation will discuss light concentration and enhancement in nanometer-scale ridge aperture antennas. Resent research, including numerical simulations and near field optical measurements has demonstrated that nanoscale ridge antenna apertures can concentrate light into nanometer domain....
