Synthesis and physicochemical properties of CuMn2O4 nanoparticles; a potential semiconductor for photoelectric devices

CuMn2O4 nanoparticles, a semiconducting materials with tunable functionalities in solid oxide fuel cell, was successfully synthesized via a sol-gel method using its respective metal cations sources i.e. Cu2+ and Mn2+ in an appropriate complexing agent.The vibrational frequencies below 1000 cm-1 of the obtained materials confirmed the formation of metal-oxygen (M-O:Cu-O, Mn-O) bond in the sample...

Modeling Semiconductor Optical Devices

In this article numerical methods used to model photonic devices are presented. In particular, the governing equations describing the problem, the coupling between electrical and optical fields, and the numerical algorithms used for computing solutions are discussed. As a computational example, we present the modeling of a semi-conductor optical amplifier employed as an all-optical demultiplexer.

Noise in Semiconductor Devices

Noise (a spontaneous fluctuation in current or in voltage) is generated in all semiconductor devices. The intensity of these fluctuations depends on device type, its manufacturing process, and operating conditions. The resulted noise, as a superposition of different noise sources, is defined as an inherent noise. The equivalent noise models (containing all noise sources) are created for a parti...
