The Cryogenic Workshop from IFGW is one of the three cryogenic facilities in the São Paulo State universities. It is responsible for providing liquid helium for all the laboratory infrastructure of IFGW where several multiuser facilities from FAPESP have been installed. This proposal has two main objectives. The first one is to complement a new helium liquefying system funded by FINEP, bu…
Van der Waals (vdW) heterostructures formed by artificially stacking transition metal dichalcogenide monolayers are one of the most attractive research playgrounds in solid-state physics nowadays. vdW heterostructures constructed with semiconductor monolayers find their niche in optoelectronics, valleytronics, and (the more recent) twistronics fundamental and applied research. Their symme…
This multi-user equipment consists in an imaging spectrometer with CCD type detector fabricated by Horiba. The main application of this system is the micro luminescence imaging of semiconductor nanostrutures. This equipment is located at the acoustic modulation laboratory in the facilities of the Group of Optical Properties (GPO) in the Gleb Wataghin Physics Institute (IFGW). It is sponso…
The generation of surface acoustic waves (SAWs) on semiconductor piezoelectric substrates, such as GaAs, allows for the application of the SAW strain and piezoelectric fields to manipulate elementary excitations (like carriers, spins, and photons) in low dimensional semiconductor nanostructures. The SAW propagating fields, besides inducing carrier transport, can be used to modulate the op…
In this project, we will address the surface acoustic wave (SAW) modulation of light-matter interaction in twisted vdW heterostructures. We will investigate how the high-frequency SAW piezoelectric potential and mechanical deformation interact with different quantum states (like intralayer, interlayer, and moiré excitons) in vdW heterostructures which have their twist angle and dielectric…
The exciton and spin-valley properties of transition metal dichalcogenide (TMD) monolayers and heterostructures have received considerable attention of the Solid-State Physics community. The lack of inversion symmetry, spin-orbit coupling and the coupling between adjacent monolayers in these two types of structures lead to a diversity of non-trivial excitonic effects associated to many bo…
The main objective of this project is to generate and detect standing wave patterns using surface acoustic waves (SAWs). In order to achieve this goal, the student will develop a software interface using Laview to control and synchronize two radio frequency generators. The generators will be connected to the two different interdigital transducers (IDTs) of a SAW delay line to generate the…
In this project, we will grow and characterize epitaxial transition metal dichalcogenide (TMD) layered systems for optoelectronics and valleytronics. By combining the growth and optical spectroscopy mutual feedback, we will investigate the effect of the growth conditions (temperature, pressure, growth rate, etc) on the structural and optical properties of different TMD monolayer samples (…

In this visiting research scholarship (BEPE) project, we will investigate the dynamics of excitonic complexes in different van der Waals heterostructures when modulated by surface acoustic waves (SAWs). In hBN/1L-MoSe2/hBN, we intend to understand an apparent population transfer between neutral excitons and trions which we have observed. This effect can be tuned and reversed by the SAW pi…
