Non equilibrium anisotropic excitons in atomically thin ReS2

Andras Kis, Andrei Kucharavy, Alessandro Surrente, Dmitry Ovchinnikov

We present a systematic investigation of the electronic properties of bulk and few layer ReS2 van der Waals crystals using low temperature optical spectroscopy. Weak photoluminescence emission is observed from two non-degenerate band edge excitonic transit ...

Revealing Large-Scale Homogeneity and Trace Impurity Sensitivity of GaAs Nanoscale Membranes

Anna Fontcuberta i Morral, Gözde Tütüncüoglu, Francesca Amaduzzi, Alessandro Surrente, Philippe Leroux

III-V nanosttuctures have the potential to revolutionize optoelectronics and energy harvesting. For this to become a reality, critical issues such as reproducibility and sensitivity to defects should be resolved. By discussing the optical properties of mol ...

Self-formation of hexagonal nanotemplates for growth of pyramidal quantum dots by metalorganic vapor phase epitaxy on patterned substrates

Elyahou Kapon, Alok Rudra, Benjamin Dwir, Romain Carron, Pascal Gallo, Alessandro Surrente

We demonstrate the self-formation of hexagonal nanotemplates on GaAs (111)B substrates patterned with arrays of inverted tetrahedral pyramids during metal-organic vapor phase epitaxy and its role in producing high-symmetry, site-controlled quantum dots (QD ...

Polarization properties and disorder effects in H-3 photonic crystal cavities incorporating site-controlled, high-symmetry quantum dot arrays

Elyahou Kapon, Alok Rudra, Benjamin Dwir, Pascal Gallo, Alessandro Surrente, Marco Felici

We report on the effects of optical disorder on breaking the symmetry of the cavity modes of H-3 photonic crystal cavities incorporating site-controlled pyramidal quantum dots (QDs) as the internal light source. The high in-plane symmetry of the polarizati ...

Ordered systems of site-controlled pyramidal quantum dots incorporated in photonic crystal cavities

Elyahou Kapon, Alok Rudra, Benjamin Dwir, Pascal Gallo, Alessandro Surrente, Marco Felici

The coupling of a prescribed number of site-controlled pyramidal quantum dots (QDs) with photonic crystal (PhC) cavities was studied by polarization and power-dependent photoluminescence measurements. The energy of the cavity mode could be readily tuned, m ...
