Abstract:
An extension of the classic thermodynamic theory to nanometer scale has generated a new interdisciplinary theory - nanothermodynamics. It is the critical tool for the investigation of the size-dependent physicochemical properties in nanocrystals. A simple and unified nanothermodynamic model for the melting temperature of nanocrystals has been established based on Lindemann’s criterion for the melting, Mott’s expression for the vibrational melting entropy, and Shi’s model for the size dependence of the melting point. The developed model has been extensively verified in calculating a variety of

Heavily doped semiconductors have emerged as low-loss and tunable materials for plasmonics at mid-infrared frequencies.

Abstract:
Dielectric permittivity has been an important property of binary and mixed semiconductor materials as it is closely related to the studies on polarization and relaxation mechanisms. Therefore, dielectric properties of (CdSe)1-X(ZnS)X mixed semiconductors are studied at different frequencies. The mixed semiconductor samples used in the study are grown by controlled co-precipitation method. From these studies ac conductivity, static and optical dielectric constants, relaxation times and activation energy of dipole relaxation are determined. The variation of dielectric constant with frequency and

Abstract:
Thieno[3,2-b]pyrrole is an effective nonconventional semiconducting building block that could be generated in gram quantities with relatively high overall yields. Three organic semiconductors containing thieno[3,2-b]pyrrole were synthesized in good yields without requiring time-consuming column purifications. The synthesis, optical and electrochemical properties were systematically investigated.1 Introduction2 Experimental3 Synthesis and Characterization4 Theoretical Calculations5 Optical and Electrochemical Properties6 Thermal Stability7 Fluorescence Experiments8 GIXRD Data9 Conclusions
