Theoretical Results

In this work, meta-material like behavior of natural Mica are studied. This work makes an attempt to analyze the left-handed Maxwellian (LHM) properties of Mica. The investigations carried out on natural Mica specimen are optical reflectance, optical absorbance and DC current–voltage-characteristics (CVC). Optical reflectance of Mica sheet with plane polarized monochromatic light shows distinct difference with conventional theoretical results. The DC CVC also measured with complete electromagnetic shielding. There exists a clear difference in DC characteristic for presence and absence of stray electromagnetic fields. The X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and ultraviolet-visible spectroscopy (UV-VIS) analysis are also carried out for further analysis. The results obtained from the optical reflectance characteristics using polarized light indicate LHM behavior as may be found in a meta-material. Micro-structural and electrical analysis shows that it is a nano-structured layered material.

Fundamental Values

In this work, we analyzed the current-voltage characteristics in the temperature range of the hybrid organic material C24H24N6O3Zn in order to determine the prospects for using this compound as a semiconductor material. The range of temperature measurements was from 270 to 330 K. An electrochemical analysis of the studied coordination compound was carried out, the energies of the HOMO and LUMO levels were calculated. The method of obtaining, microscopy, and also the method of measuring the temperature dependences of the electrical properties of the obtained thin films of these hybrid materials based on zinc complexes are described. A number of fundamental values of the films of this coordination compound have been calculated: the activation energy is  0.88 eV and the mobility of charge carriers is  1.4710-11 cm V-1 s-1.

Average Cluster

Gadolinium (Gd) is a weak magnetic element at room temperature. Gadolinium oxide (Gd2O3) is a poor semiconductor with para-magnetism. In this work Gadolinium oxide is prepared from the thermal dissociation of Gadolinium acetate. The average cluster size is found to be dependent on the number of the sintering time. In this present work an attempt has been made to characterize the developed Gadolinium oxide. Experimental probes used to characterize it are optical absorbance (UV-VIS); Fourier transformed infra red (FTIR) spectroscopy, DC current voltage characteristics (CVC) and photo-sensitivity studies of the developed specimens. Gadolinium oxide exhibits a good optical sensing property.
