GaAs droplet quantum dots with nanometer-thin capping layer for plasmonic applications
Suk In Park, Oliver Joe Trojak, Eunhye Lee +6
We report on the growth and optical characterisation of droplet GaAs quantum dots with extremely-thin (11 nm) capping layers. To achieve such result, an internal thermal heating st…
Fabrication and tuning of plasmonic optical nanoantennas around droplet epitaxy quantum dots by cathodoluminescence
Gilles Nogues, Quentin Merotto, Guillaume BACHELIER +2
We use cathodoluminescence to locate droplet epitaxy quantum dots with a precision nm before fabricating nanoantennas in their vicinity by electron-beam lithography. Cat…
Directional terahertz emission from diffusion-engineered InAs structures
Jong-Hyuk Yim, Hoonil Jeong, Jin-Dong Song +1
We have designed and fabricated a new type of terahertz (THz) emitter that radiates THz waves along the surface-normal direction because of the lateral distributions of the transie…
Nexus between directionality of THz waves and structural parameters in groove-patterned InAs
Jong-Hyuk Yim, Kyunggu Min, Hoonil Jeong +2
We have performed terahertz (THz)-time domain spectroscopy in various geometries, for characterizing the directivity of THz waves emitted from groove-patterned InAs structures. Fir…
