Tunable light emission from quantum-confined excitons in TiSi2-catalyzed silicon nanowires.
Visible and near-infrared photoluminescence (PL) at room temperature is reported from Si nanowires (NWs) grown by chemical vapor deposition from TiSi2 catalyst sites. NWs grown with average diameter of 20 nm were etched and oxidized to thin and passivate the wires. The PL emission blue shifted continuously with decreasing nanowire diameter. Slowed oxidation was observed for small nanowire diame...
متن کاملMoiré excitons: From programmable quantum emitter arrays to spin-orbit–coupled artificial lattices
Highly uniform and ordered nanodot arrays are crucial for high-performance quantum optoelectronics, including new semiconductor lasers and single-photon emitters, and for synthesizing artificial lattices of interacting quasiparticles toward quantum information processing and simulation of many-body physics. Van der Waals heterostructures of two-dimensional semiconductors are naturally endowed w...
متن کاملTunable multiband metasurfaces by moiré nanosphere lithography.
Moiré nanosphere lithography (MNSL), which features the relative in-plane rotation between two layers of self-assembled monodisperse nanospheres as masks, provides a cost-effective approach for creating moiré patterns on generic substrates. In this work, we experimentally and numerically investigate a series of moiré metasurfaces by MNSL. Due to the variety of gradient plasmonic nanostructures ...
متن کاملTrapped-ion quantum simulation of tunable-range Heisenberg chains
Quantum-optical techniques allow for generating controllable spin-spin interactions between ions, making trapped ions an ideal quantum simulator of Heisenberg chains. A single parameter, the detuning of the Raman coupling, allows to switch between ferromagnetic and antiferromagnetic chains, and to modify the range of the interactions. On the antiferromagnetic side, the system can be tuned from ...
متن کاملThe binding energy of light excitons in spherical quantum dots under hydrostatic pressure
We study the effects of hydrostatic pressure over the ground state binding energy of light hole excitons confined in GaAs − Ga1−xAlxAs spherical quantum dots. We applied the variational method using 1s-hydrogenic wavefunctions, in the framework of the effective mass approximation. We computed the exciton binding energy as a function of the dot radius, Al concentrations and pressures. Our result...
