PT symmetric Floquet topological phase in SSH model
(Elsevier Science Bv, 2018)
We consider periodically modulated Su-Schrieffer-Heeger (SSH) model with gain and loss. This model, which can be realized with current technology in photonics using waveguides, allows us to study Floquet topological ...
Spectrum Analysis of GMA Welter in Various Working Modes
(Budapest Tech, 2012)
In this study, a current drawn by a welter at initial, stable-state and finish modes is examined using spectral analysis. The current shunt measurement method is utilized in order to measure the current drawn by the welter. ...
Structural investigation of AlInN/AlN/GaN heterostructures
(Springer, 2016)
AlInN/AlN/GaN high-electron-mobility transistor (HEMT) structures were grown on undoped-GaN-layers/sapphire templates by metal-organic chemical vapor deposition to investigate the properties of HEMTs with various thickness ...
