This thematic project aims to establish the conceptual bases and training of human resources necessary for the development of Second Generation Quantum Technologies by structuring a value-proposition to the market of industrial and service companies worldwide.Second Generation Quantum Technologies comprise solutions that directly benefit from quantum states of light or matter, such as sup…
Semiconductor nanostructures with a one-dimensional quantum confining potential profile, such as resonant tunneling diodes (RTD), are highly employed in devices intended for wide industrial applicability and basic science. However, the optical emission of these devices to date has been found in a narrow spectral range dominated by the precursors materials that form them. The opto-electron…
The time correlated single photon couting (TCSPC) technique is the most sensitive method for determining photoluminescence/fluorescence lifetimes. TCSPC is based on the detection of single photons after optical excitation of a sample by a pulsed source. The light from the source starts the electronics, which is stopped after the photons from the samples reaches the detector. The time diff…

Samples with different geometries and composition will be used in the investigation and the search for quantum effects with potential application in devices. The project also includes the collaboration among groups of growth, structural …
Two-dimensional materials have emerged as a major focus of academic research over the past two decades, both for studying their fundamental properties and for developing nano-structured devices. Among these materials, transition metal dichalcogenides (TMDs) stand out as promising two-dimensional semiconductors due to properties such as having a direct bandgap in their monolayer form and e…
Low-dimensional Nanostructures, such as quantum wells and dots, have received great attention from the scientific community over the last decades from the point of view of Basic and Applied Physics. On that perspective, recent improvements on growing antimony-based systems allowed the introduction of this element in the traditional III-V alloys, opening a wide range of new study possibili…
Quantum dots (QDs) based on the In(Ga)As alloy are the basis of several technologies and promising candidates for applications in the field of quantum information. The growth of these nanostructures by the Stranski-Krastanov method also induces the formation of the so-called wetting layer (WL), which can deteriorate several optoelectronic properties of quantum dots. A viable alternative f…
Among the several optical techniques used on materials analysis, one of the most used is called Raman spectroscopy. The Raman method consists on studying the inelastically scattered light by a specimen after its excitement through a light source, whose scattering may contain data about both structural and electronic parts of the structure. The main advantages of this procedure are the gat…

Recent advancements in growth techniques involving antimony-based nanostructures have sparked considerable interest in incorporating them into traditional III-V semiconductor systems. This pursuit is driven by their ability to shift optical emissions towards telecommunication wavelengths, reduce strain, enhance spin-orbit coupling effects, and enable different band alignments. Such featur…
Recent efforts to improve antimony-based nanostructures growth techniques have allowed its incorporation on the traditional III-V semiconductor systems, opening an ample field for investigations on Condensed Matter Physics. Their relevance dwells on the optical emission dislocation towards telecom wavelengths (1.2 - 1.6 ¼m), strong spin-orbit coupling and possibility of type-II band align…
This project aims at developing efficient spin-photon interfaces for short-term to long-term quantum applications. To engineer a controlled interaction between a stationary spin qubit and optical photons, we will use semiconductor quantum dot-cavity systems with a unique geometry based on micropillar cavities, deterministically coupled to InAs quantum dots, to exploit the giant polarizati…
