Optimal metal domain size for photocatalysis with hybrid semiconductor-metal nanorods

Semiconductor-metal hybrid nanostructures offer a highly controllable platform for light-induced charge separation, with direct relevance for their implementation in photocatalysis. Advances in the synthesis allow for control over the size, shape and morphology, providing tunability of the optical and electronic properties. A critical determining factor of the photocatalytic cycle is the metal ...

Recent Developments in the Synthesis of Metal-Tipped Semiconductor Nanorods

Semiconductor nanocrystals (NCs), commonly known as quantum dots (QDs), have received great attention over the last two decades due to their, unique size and shapedependent optoelectronic properties, as well as their flexible surface chemistry. While efforts to produce colloidal NCs date back to the pioneering work of Rossetti et al at Bell Labs1 and Ekimov et al at the Vavilov State Optical In...

Quantum Beats in Hybrid Metal−Semiconductor Nanostructures

We investigate nonradiative quantum coherence in the presence of coupling between excitons and surface plasmon polaritons (SPPs) in a hybrid metal−semiconductor nanostructure. In particular, we study how quantum coherence between heavy-hole (HH) and light-hole (LH) excitons in a GaAs quantum well (QW) is modified when they are coupled to SPPs of a gold grating. We find that the nonradative cohe...

Plasmonic Nanoslit Enhanced Metal-Semiconductor-Metal Photodetectors

We computationally show that metallic nanoslitsintegrated on Germanium metalsemiconductor-metal photodetectors show absorption enhancement up to 8 for TM-polarization in the communications C-band due to interference of horizontal surface plasmons. OCIS codes: 040.5160; 130.0250; 250.5403 Semiconductor industry has continuously scaled down electronic devices, significantly improving device leve...
