Hyper-doping of Silicon for Plasmonics in the Telecommunication Range
Jura Rensberg, Angela Barreda, Kevin Wolf +6
We investigate hyper-doping, a promising approach to introduce a high concentration of impurities into silicon beyond its solid solubility limit, for its potential applications in…
Heavily doped zinc oxide with plasma frequencies in the telecommunication wavelength range
Alexander Koch, Hongyan Mei, Jura Rensberg +10
We demonstrate heavy and hyper doping of ZnO by a combination of gallium (Ga) ion implantation using a focused ion beam (FIB) system and post-implantation laser annealing. Ion impl…
Tuning carrier density and phase transitions in oxide semiconductors using focused ion beams
Hongyan Mei, Alexander Koch, Chenghao Wan +10
We demonstrate spatial modification of the optical properties of thin-film metal oxides, zinc oxide and vanadium dioxide as representatives, using a commercial focused ion beam (FI…
Fast recovery of ion-irradiation-induced defects in Ge2Sb2Te5 thin films at room temperature
Martin Hafermann, Robin Schock, Chenghao Wan +3
Phase-change materials serve a broad field of applications ranging from non-volatile electronic memory to optical data storage by providing reversible, repeatable, and rapid switch…
Optical properties of thin-film vanadium dioxide from the visible to the far infrared
Chenghao Wan, Zhen Zhang, David Woolf +13
The insulator-to-metal transition (IMT) in vanadium dioxide (VO2) can enable a variety of optics applications, including switching and modulation, optical limiting, and tuning of o…
