Terahertz photodetection in scalable single-layer-graphene and hexagonal boron nitride heterostructures
M. Asgari, L. Viti, O. Balci +12
The unique optoelectronic properties of single layer graphene (SLG) are ideal for the development of photonic devices across a broad range of frequencies, from X-rays to microwaves…
Quantum-dot single-electron transistor as thermoelectric quantum detectors at terahertz frequencies
Mahdi Asgari, Dominique Coquillat, Guido Menichetti +6
Low dimensional nano-systems are promising candidates for manipulating, controlling and capturing photons with large sensitivities and low-noise. If quantum engineered to tailor th…
Fast and Sensitive Terahertz Detection Using an Antenna-Integrated Graphene pn Junction
Sebastián Castilla, Bernat Terrés, Marta Autore +11
Although the detection of light at terahertz (THz) frequencies is important for a large range of applications, current detectors typically have several disadvantages in terms of se…
Thermoelectric terahertz photodetectors based on selenium-doped black phosphorus flakes
Leonardo Viti, Antonio Politano, Kai Zhang +1
Chemical doping of bulk black phosphorus is a well-recognized way to reduce surface oxidation and degradation. Here, we report on the fabrication of terahertz frequency detectors c…
Plasmonics with two-dimensional semiconductors "beyond graphene": from basic research to technological applications
Amit Agarwal, Miriam S. Vitiello, Leonardo Viti +2
In this minireview, we explore the main features and the prospect of plasmonics with two-dimensional semiconductors. Plasmonic modes in each class of van der Waals semiconductors h…
Terahertz detection of magnetic field-driven topological phase transition in HgTe-based transistors
A. Kadykov, F. Teppe, C. Consejo +12
We report on Terahertz detection by inverted band structure HgTe-based Field Effect Transistor up to room temperature. At low temperature, we show that nonlinearities of the transi…
