This thesis reports on the investigations performed on electrochemical functionalization and photoelectronic transport properties of individual single-wall carbon nanotubes (SWCNTs). The first part of the thesis is concerned with the controlled modificatio ...
Electrical transport studies on graphene have been focused mainly on the linear dispersion region around the Fermi level(1,2) and, in particular, on the effects associated with the quasiparticles in graphene behaving as relativistic particles known as Dira ...
The underlying physical mechanism of the so-called colossal dielectric constant phenomenon in CaCu3Ti4O12 CCTO thin films were investigated by using semiconductor theories and methods. The semiconductivity of CCTO thin films originated from the acceptor de ...
The utilization of functional organic materials holds great promise for applications in electronic devices. Semiconducting organic molecules are frequently used as channel material in field effect transistors, due to the ease by which they can be assembled ...
A technique to deterministically manipulate individual Carbon Nanotubes (CNT) has been the brick-wall for the boom of CNT based devices. Here we demonstrate dielectrophoresis as an efficient technique to trap individual Single Walled Carbon Nanotubes (SWCN ...
Germanium metal-insulator-semiconductor capacitors with La2O3 dielectrics deposited at high temperature or subjected to post deposition annealing show good electrical characteristics, especially low density of interface states D-it in the 10(11) eV(-1) cm( ...
We present a theoretical study of the physical characteristics of metal/semiconductor junctions. Using first principle pseudopotential calculations, we have investigated the nature of electronic states with energies within the semiconductor band gap of rep ...
Carbon nanotubes are novel materials with unique electrical and mechanical properties. Here we present results on their atomic structure and mechanical properties in the adsorbed state, on ways to manipulate individual nanotubes, on their electrical proper ...
We have modified the Schottky-barrer height of Si overlayers on Ag(111) substrates by means of Cs intralayers of different thicknesses. We also found a correlation between these changes and those of the work function, which makes it possible to measure the ...
We study the properties of gold contacts on chemically derived graphene devices by scanning photocurrent microscopy and gate-dependent electrical transport measurements. In the as-fabricated devices, negligible potential barriers are found at the gold/grap ...
