III-V Semiconductor nanostructures with the incorporation of the antimony element stand out for their strong spin-orbit coupling, which results are interesting for spin physics in optoelectronic experiments. Thanks to the improvement in growth techniques, the recent quality achieved in the growth of these materials has driven attention from the scientific community in this field. This pro…
The present project deals with three main problems. The first one is related to electron-acoustical phonon interaction in core-shell Ge/Si and Si/Ge nanowires (NWs), the second topic is linked to research on the exciton-polaritons in the novel 2 dimensional dichalcogenide semiconductors, MoS2 and Ws2, placed in a planar microcavity, and the third one provides the grounds for understanding…
This multiuser equipment comprises an ultra-low vibration helium closed cryostat operating between 4.5 and 300 K with applying magnetic fields up to 9 T, and the confocal microscopy technique associated. The sample is placed in the uniform magnetic field region at the top of piezoelectric x-y-z-stages, and an objective lens compatible with cryogenic temperatures is used for focusing light…

The central aim of the proposal is to assemble and characterize 2D materials with photochromic bending molecules for the realization of multifunctional atomically thin optoelectronic devices.Bulk semiconductors currently used in electronic devices have intrinsic drawbacks: are rigid, heavy in weight, limited size shrink and require the use of high cost technology to be processed. Thus, r…
This project is guided to the preparation of a student to work in transport properties in a near future. It is intended to initiate and solidify analytical methods and knowledge for advanced numerical techniques. The candidate should calculated transmissivity and tunneling current in double-barrier systems. He will work with two models for the potential profile under applied voltage, …
This project has as main objective to study the properties of carriers confined in single and coupled quantum ring nanostructures. In particular, we will focus on the dynamics of the carriers, including spin-dependent properties and electron-phonon interactions. We will also investigate how the geometry and the presence of external fields affect the carrier behavior. Furthermore, we will …
