“…THz continuous wave (CW) sources are compact, but spectral scanning requires time. THz CW sources include ultrafast highspeed transistors [101], resonant tunneling diodes [102], quantum cascade lasers (QCLs) [103], backward wave oscillators [104], Schottky diodes [105], electro-optically active dendrimers [106], and optoelectronic devices [107]. THz CW wave detection can be realized with bolometers [108], pyroelectric detectors [109], Schottky diodes [110], and other optoelectronic detectors [111].…”

This review considers glioma molecular markers in brain tissues and body fluids, shows the pathways of their formation, and describes traditional methods of analysis. The most important optical properties of glioma markers in the terahertz (THz) frequency range are also presented. New metamaterial-based technologies for molecular marker detection at THz frequencies are discussed. A variety of machine learning methods, which allow the marker detection sensitivity and differentiation of healthy and tumor tissues to be improved with the aid of THz tools, are considered. The actual results on the application of THz techniques in the intraoperative diagnosis of brain gliomas are shown. THz technologies’ potential in molecular marker detection and defining the boundaries of the glioma’s tissue is discussed.

“…The temperature dependence of a pn-junction diode, however, is quite different from that of a Schottky barrier diode due to the different carrier transport mechanisms involved [3]. The physical based Schottky barrier diode model recently developed at the Technical University of Denmark and Goethe University of Frankfurt am Main [4] should in principle be able to predict the temperature behavior at cryogenic temperatures. The physical diode model, however, requires detailed knowledge about the technology used to fabricate the device.…”

Abstract-We report on the evaluation of Schottky barrier diode GaAs multipliers at cryogenic temperatures. A GaAs Schottky barrier diode model is developed for theoretical estimation of doubler performance. The model is used to predict efficiency of doublers from room to cryogenic temperatures. The theoretical estimation is verified experimentally using a 78 GHz doubler cooled down to 14 K. The observed efficiency improvement due to cooling is approximately 4 % per 100 degrees.
