The speed of detectors represents a crucial point in the definition of the communication system using THz carrier. Rectification performed by MOS structures was usually detected by lock-in amplifiers, thus appears quite slow. We show by theoretical a

The mechanisms of THz rectification performed by the JLFET detector are studied by TCAD simulations, in the light of the self-mixing model. Results show a new picture of the device functioning giving a new description of measured response. The achiev

We present a systematic study of time resolution and power dependence of the responsivity of three significantly different types of the Field Effect Transistor based detectors. We analyze photoresponse of custom-made Si junctionless FETs (JLFETs), Si

A new type of JLFET based detector is described in the paper. This JLFET is equipped with additional electrode contacting side of the channel (giving T-like shape of the channel). The device offers higher photoresponse and better SNR and NEP than its

Recently, there is a growing interest in piezoelectric layers and their application in micro – electro – mechanical systems (MEMS). MEMS containing piezoelectric layers are simple in build and easy to control. This paper focuses on application of

Two models of the THz electromagnetic radiation detection using field-effect devices are presented and briefly discussed with regard to junctionless FETs as THz detectors. Due to inconsistency between a plasmonic theory and JLFET characteristics, a r

We studied time resolution and response power dependence of three terahertz detectors based on significantly different types of field effect transistors. We analyzed the photoresponse of custom-made Si junctionless FETs, Si MOSFETs and GaAs-based hig

This paper describes a THz detector based on junctionless FET with integrated 340GHz patch antenna and cascode preamplifier. 20dB cascode gain was measured. It is essential that the preamplifier can work with a single bias and consume small power of
