OPTO AND NANOELECTRONICS
OLABs is the research group at the Department of Electronics Engineering of the University of Rome "Tor Vergata" working of the design, fabrication and characterization of active optoelectonic and nanoelectronic devices.
Established in 1994, the research group has five permanent staff members, a CNR researcher and several postdocs and PhD students.
The group is involved in national and international research projects. One of the main activities of OLAB is the development of hybrid and organic solar cells within the Regional centre CHOSE.
Large effort is also devoted to the simulation of nanoelectronic and conventional electronic devices. Simulation tools developed at OLAB are availabe on the computation-on-demand portal ICODE. The group is involved in the development of TiberCAD, a multiscale CAD tool for the simulation of nanoelectronic devices.
FABRICATION AND CHARACTERIZATION ACTIVITIES
Experimental activities mainly focus on the realization of active optoelectronic devices and nanoelectronic devices. Solar cell are realized by using both small molecules, polymers and Dyes. A 100 sqm clean room is under construction and two labs are devoted to the characterization of devices. Carbon nanotube based vacuum tubes are realized by using a interdipartimental consortium named MINAS. In vacuum tubes, CNTs are used as cold cathodes while grids and anodes are realized by using micromachining techniques.
SIMULATION AND DESIGN ACTIVITIES
OLABs is involved in the development of a Open Source code for the multiscale simulation of nanoelectronics devices. TiberCAD is the name of the tool and has been recently applied to the simulation of electrical injection in Polariton Laser - a new Laser structure based on the Bose-Einstein condensation of Polaritons. TiberCAD together with conventional device simulations tools is actively used to the simulation and optimization of High Electron Mobility Transistors based on Gallium Nitride.
Molecular Electronics is also one of the leading activities of OLABs. A first-principle transport simulator, gDFTB, has been developed and applied to several molecular devices such as Carbon Nanotubes and small molecules between contacs.
