- ANM 2018 advanced nano materials, AR.EXT
- Coherent electron and hole dynamics in semiconductor rings, AV.EXT
Abstract
Developments in materials synthesis and processing have allowed, for some time, the exploration of coherent electron dynamics in condensed matter systems. These studies, typically at low-temperatures and in highly pure and defect-free systems, reveal interesting properties in materials themselves. However, and perhaps more interestingly, these studies also probe the detailed quantum mec...
- Optical and transport phenomena in Nano-devices, AP.R
Abstract
This proposal foresees the search and development of nanoscale electro-optical semiconductor devices and the systematic study of their optical and transport properties. The goals set now are framed within the scope of a collaborative work between the experimental growth, electro- optical spectroscopy, and theoretical calculations. Previous projects allowed the evolution of our research ...

- Many-body effects on Valley qubits and on the magneto-optical properties of transition metal dichalcogenide monolayers, BP.PD
Abstract
The fabrication and characterization of graphene, in 2004, have opened new paths to the realization of a truly two-dimensional gas, with great perspectives to study both fundamental and applied physics related to quantum Hall effect, fractional quantum Hall effect, quantum anomalous Hall effect, quantum spin Hall effect, topological insulators, etc. Due to the low dimensionality and the...

- Carrier transport through photo-gated thin exfoliated dichalcogenide films, BE.EP.DR
Abstract
Transition-metal dichalcogenides thin crystals rise as potential building blocks of thin electro-optical devices. Their electronic structure can be locally modified applying local stress or local electrostatic potentials (gates) to induce the appearance of barriers and/or wells for carrier confinement. Given the feasible manipulation of these quasi-2D systems, they can be used as thin f...

Abstract
This project proposes a sequence of tasks related to the systematic investigation of structural and electronic properties of bulk and nanostructured semiconductor prepared on the base of the II-VI materials, with and without manganese (Mn) incorporation. We will follow three major fields of investigation: i) Calculation of structural and electronic properties of bulk CdSe, such as wave ...
