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…
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 project we aim to optimize, fabricate, and characterize interdigital transducers (IDTs) for surface acoustic wave (SAW) generation. Our final goal is to fabricate functional unidirectional devices (FEUDTs). In the first part of the project, the student will review the theoretical background of conventional IDT fabrication in order to optimize the physical characteristics of his de…
This project aims to implement a micro-photoluminescence (micro-PL) spatial mapping system in the acoustic wave modulation lab of the Group of Optical Properties (GPO) from IFGW. The main objective is to perform space and energy-resolved micro-PL in different semiconductor nanostructures. The mapping will allow a detailed study of micro-PL in nanostructures (like 2D materials) and the eff…
We will investigate the vibrational properties of heterostructured InAsP and InAsP/InP nanowires by Raman spectroscopy. Nanowires were grown by VLS method catalized with gold nanoparticles. In InAsP nanowires, we will identify the Raman active modes for different alloy compositions by selecting the incident and scattered light polarization conditions. In the heterostructured nanowires, th…
