In the present work, we report on resolution enhancement of a terahertz imaging system using the terajet effect. A wavelength-scaled particle (a Te on cube for simplicity) was used to localize incident radiation to a subwavelength volume and focus it

We report on a study of the coupling of electromagnetic radiation to a strained-silicon MODFETs used as sub-THz terahertz detector. In particular, the effect of the polarization of the incoming beam as well as the role of the bonding wires on the pho

[EN] This paper reports on a study of the response of a T-gate strained-Si MODFETs (modulation-doped field-effect transistor) under continuous-wave sub-THz excitation. The sub-THz response was measured using a two-tones solid-state source at 0.15 and

We report on detection of terahertz radiation by using asymmetric dual-grating gates graphene-based FET. The graphene sheet was sandwiched between two layers of hexagonal Boron Nitride (h-BN) to avoid interaction with the substrate and enhance carrie

This paper reports on the study of strained-Si n-channel MODFETs as detectors of sub-THz radiation. Simulations based on a bi-dimensional hydrodynamic model for the charge transport coupled to a Poisson equation solver were performed. A charge bounda

[EN] Herein, a simple terahertz (THz) receiver that uses subwavelength focusing of the THz beam on the detector area is proposed. As a proof of concept, a THz detection system with an original optical coupling scheme is implemented, where the signal

Thickness of Si solar cells is being reduced below 200 µm to reduce costs and improve their performance. In conventional solar cells recombination of photo-generated charge carriers plays a major limiting role in the cell efficiency. High quality th
