Electrical And Magnetic Properties Of Polyvinylchloride - Amorphous Carbon / Iron Carbide Nanoparticle Comosites
(2009-05-18)The UV-Visible spectra of a-C composites and nano composites have provided a very useful information about the electronic states and band structure. The UV-Visible spectra of a-C as well as nanoparticle are qualitatively ... -
Electrical resistance and dielectric constant studies in a binary liquid system in the critical region
This thesis presents an experimental investigation of electrical resistance and dielectric constant anomalies in a critical binary liquid system (the polar + non-polar mixture methanol + cyclohexane). Since the critical ... -
Experimental investigations on metal-insulator transition and structure in amorphous carbon films
Conductivity of carbon films prepared from TCPA at pyrolysis temperatures of 700°C, 800°C, and 900°C was measured by varying the temperature between 1.4 K to 300 K. To study the effect of substrates, films were deposited ... -
Mossbauer, Magnetization And Electrical Transport Studies On Iron Nanoparticles Embedded In The Carbon Matrix
(2009-08-19)This thesis deals with the studies of magnetization and electrical transport properties of iron nanoparticles embedded in the carbon matrix. The synthesis and characteristics of the nanoparticle systems studied, are also ... -
Synthesis, Characterization and Electrical Transport In Carbon Nanotubes
(2011-08-05)In this thesis, synthesis, characterization and electrical transport of Carbon nanotubes (CNTs) have been discussed. The first chapter contains a brief introduction of various forms of carbon including CNT. The CNTs are ...
