Transport spectroscopy and control of molecular quantum dots
… of such molecular quantum dots inside the transport junction, which can deviate significantly from those of the isolated dot due to the close proximity of the large electrodes. Here the transport current through the system can act as a tool to investigate its properties, i.e., a transistor …

Transport spectroscopy of graphene quantum dots fabricated by atomic force microscope nano-lithography
… AFML to fabricate graphene quantum dot systems. Transport measurements are carried out on our graphene quantum dots at low temperatures and high parallel magnetic fields and we try to understand the behaviour of spins in graphene. In our initial investigations into AFML we use graphene samples …

Characterization of Poly(ethyleneimines) by Electrohydrodynamic Ionization Mass Spectrometry and Investigations of the Mechanism of Surfactant-Sensitization of Metal-Chrome Azurol S Complexes (Sampling, Transport, Spectroscopy, Micelle)
Molecular weight distributions of poly(ethyleneimines) (PEIs) were characterized by Electrohydrodynamic Ionization (EH) Mass Spectrometry to determine the effect of both the chemical structure and the solution chemistry of the polymer on its sampling behavior from glycerol.

Parallel Fabrication and Transport Properties of Carbon Nanotube Single Electron Transistors
… nanotubes (SWNTs) and studied their electron transport properties. The approach is based on the assembly of individual SWNTs via dielectrophoresis (DEP) at the selected position of the circuit and formation of tunnel barriers on SWNT. Two different techniques: i) metal-SWNT Schottky contact, …

On the Dynamics of Single-Electron Tunneling in Semiconductor Quantum Dots under Microwave Radiation
… gas (2DEG) of AlGaAs/GaAs heterostructures. For transport studies, quantum dots are coupled to the drain and source contacts via tunnel barriers. Electron-electron interaction in such closed quantum dots leads to Coulomb-blockade (CB) effect and single-electron tunneling (SET) through discrete …

Quantum transport through single molecules
… theoretical description and analysis of electron transport through single molecules. Therefore transport models are developed that take into account the special magnetic, electronic and electro-chemical properties of the molecules of interest. One advantage of this approach is that model …
