Ultrafast modulation in a THz graphene-based flat absorber through negative photoconductivity
Anna C. Tasolamprou, Anastasios D. Koulouklidis, Christina Daskalaki +9
We present the experimental and theoretical study of an ultrafast graphene based thin film absorption modulator for operation in the THz regime. The flat modulator is composed of a…
The Software-Defined Metasurfaces Concept and Electromagnetic Aspects
Anna C. Tasolamprou, Alexandros Pitilakis, Odysseas Tsilipakos +17
We present the concept and electromagnetic aspects of HyperSurFaces (HSFs), artificial, ultrathin structures with software controlled electromagnetic properties. The HSFs key unit…
Efficient and environmental-friendly perovskite solar cells via embedding plasmonic nanoparticles: an optical simulation study on realistic device architecture
George Perrakis, George Kakavelakis, George Kenanakis +4
Solution-processed, lead halide-based perovskite solar cells have overcome important challenges over the recent years, offering low-cost and high solar power conversion efficiencie…
