The electrical properties of plasma deposited nanocomposite thin films based on graphite-like nanoparticles embedded in a hydrogenated amorphous carbon matrix were studied. In contrast with classical dielectric materials, dielectric losses present a relaxation peak dependent on white light intensity. The latter is attributed to nanoparticles that are responsible for this photo-excited mechanism.
In this work we present the remote control of the tank level system. The physical system is controlled in real time using local or Internet network. The client could manage the remote experiment through a simple web browser via a graphical shared user interface. The study is based on the PID identification parameters according to Ziègler-Nichols methods. After the identification of the PID parameters...
In this paper, a remote temperature control system has been proposed. The physical system is controlled in real time through the Internet network. For educational purpose, the students use only a web browser to tune and test a PID controller via shared user interface. The PID parameters are calculated using the basic experimental Ziegler—Nichols tuning rules. After hardware and software experiment...
Amorphous hydrogenated carbon (a-C:H) thin films have been deposited from pure methane discharges in Microwave Multipolar Plasma excited at Distributed Electron Cyclotron Resonance (MMP-DECR). Investigations on the effect of process parameters on the film physico-chemical and electrical properties have been carried out. The plasma discharge power has a significant effect on the film density and on...
