“…Along with the electronic properties, SiC allows for advantageous replacement of Si by SiC in a wide range of specific application fields. They are ranging from applications as a functional ceramic material [1], in microelectromechanical systems (MEMS) [2,3] through applications in electronics [4] and sensorics [4][5][6][7][8] to quantum electronics and photonics [9,10]. Every application field requires specific solutions of the SiC synthesis, deposition or growth as well as the integration into a process flow.…”

Silicon carbide layers were fabricated using self-propagating high-temperature synthesis of binary silicon-carbon based reactive multilayers. The silicon and carbon bilayers were fabricated with two different bilayer thicknesses. They are deposited by magnetron sputtering in an alternating layer system with a total thickness of 1 μm. The entire system is annealed by rapid thermal annealing at different temperatures ranging from 500 to 1100 °C. From XRD analysis we could find that the formation of the silicon carbide phase was initiated from 700 °C. With increasing bilayer thickness the silicon carbide phase formation was partially suppressed by the silicon recrystallization due to resulting lower carbon diffusion into silicon. The transformation process proceeds in a four-step process: densification/recrystallization, interdiffusion, nucleation and transformation. From this, it was noted that when compared to low bilayer thickness samples, the formation of the silicon carbide phase is delayed with increasing bilayer thickness and needs higher reaction initiation temperatures.

“…Two examples of digital light signals with Manchester coding are shown in Fig. 9 The scatter graph also shows that the front and back signal are inversely correlated, due to the negative slope of the graphs [28] as expected due to each digital light signal being a composition of a short and long wavelength [29].…”

The photosensor studied in this document, is an amorphous silicon structure deposited on transparent glass allowing illumination on both sides. It responds to wavelengths from near infrared range to the ultraviolet. The front illumination surface is used for inputting light signal. The dynamic characteristics of the photosensor are altered by using optical bias on either surface of the sensor, thus the same input results in different outputs. Experimental studies made with the photosensor evaluate its applicability as a multiplexer, demultiplexer and logical operations device. A memory effect was observed. A programmable pattern emission system, and a validation and recovery system were built to illuminate the sensor with input light signals and to analyze the resulting output.
