Effect of generation rate on transient photoconductivity of semi-insulating 4H-SiC
Autor: Marek Suproniuk, Mariusz Wierzbowski, Piotr Paziewski
Publikováno v: Scientific Reports, Vol 10, Iss 1, Pp 1-14 (2020)
Abstract The effect of generation rate on transient photoconductivity of semi-insulating (SI) 4H-SiC is discussed. The rate of generation of electron–hole pairs is dependent on the number of photons incident on the sample material and its absorptio

Machine Learning Algorithms for Prediction of the Quality of Transmission in Optical Networks
Autor: Stanisław Kozdrowski, Paweł Cichosz, Piotr Paziewski, Sławomir Sujecki
Publikováno v: Entropy, Vol 23, Iss 1, p 7 (2020)
Increasing demand in the backbone Dense Wavelength Division (DWDM) Multiplexing network traffic prompts an introduction of new solutions that allow increasing the transmission speed without significant increase of the service cost. In order to achiev
