DC Electric Field Effects on the Electron Dynamics in Double Rectangular Quantum Dots
Coupled quantum dots DC bias Coherence Relaxation
2010/9/25
The effect of a dc electric field on the temporal evolution of an electron in a double rectangular quantum dot is explored in this work. In the framework of the effective mass approximation, first-ord...
The Effect of Preparation conditions on the Growth Rate of Films, the Yield of Precipitated Powder and the DC Conductivity of Polypyrrole
DC Conductivity Conducting Polymers Polypyrrole Quartz Crystal Microbalance Technique
2010/4/12
Polypyrrole (PPy) was prepared by a chemical method by using oxidizing agents ferric chloride and potassium persulphate, both as films and pellets. The effect of various variables-such as aging of the...
Nitriding of AISI 304 Stainless Steel by PIII in DC and RF Toroidal Discharges
AISI 304 Stainless Steel PIII DC and RF Toroidal Discharges
2010/10/27
Plasma immersion ion implantation (PIII) of stainless steels with nitrogen has been successfully used for surface hardening purposes. This process has been carried out inside a toroidal discharge cham...
