Terahertz emission from a weakly-coupled GaAs/AlGaAs superlattice biased into three different modes of current self-oscillations
Autor: G. K. Rasulova, I. V. Pentin, G. N. Goltsman
Publikováno v: AIP Advances, Vol 9, Iss 10, Pp 105220-105220-8 (2019)
Radio-frequency modulated terahertz (THz) emission power from weakly-coupled GaAs/AlGaAs superlattice (SL) has been increased by parallel connection of several SL mesas. Each SL mesa is a self-oscillator with its own oscillation frequency and mode. I

Autor: D. M. Ruzieva, T. G. Gulyamova, R. S. Sattarova, SM Masmetova, LA Abdulmyanova, G. A. Rasulova, KV Lobanova
Publikováno v: International Journal of Engineering, Science and Technology. 5:19-24
Lovastatin production by Aspergillus terreus indigenous strains in submerged (SmF) and solid state fermentations (SSF) have been studied. To evaluate the ability to produce lovastatin various cultivation media and substrates have been used. The obtai

The study of the bolometer response to terahertz (THz) radiation from a double-barrier resonant tunneling diode (RTD) biased into the negative differential conductivity region of the I–V characteristic revealed that the RTD emits two pulses in a pe

Mutual synchronization of two coupled self-oscillators based on GaAs/AlGaAs superlattices

The interaction of self-oscillators based on 30-period weakly coupled GaAs/AlGaAs superlattices is studied. The action of one self-oscillator on the other was observed for a constant bias voltage in the absence of generation of self-sustained oscilla

Higher harmonics in the current oscillations in weakly coupled GaAs/AlGaAs superlattices
Autor: N. P. Brunkov, G. K. Rasulova, A. E. Zhukov, V. M. Ustinov
Publikováno v: Semiconductors. 40:825-828
It is shown that the self-sustained oscillations observed in weakly coupled GaAs/AlGaAs superlattices result from the superposition of sinusoidal oscillations of several coupled oscillators. Each oscillator is a single-barrier resonant tunneling diod
