The thermal properties of freely suspended GaAs nanowires are investigated by applying a method which relies on laser heating and the determination local temperature Raman spectroscopy. In order to determine values for conductivity κ, fraction power absorbed inside nanowire is estimated numerical simulations. with homogeneous diameter found lie in range 8–36 W m−1 K−1. change profile presence tapering was investigated. Furthermore, we discuss influence ambient conditions value κ.
This paper analyses optimal electricity investments (PV and battery storage) to decarbonise heat supply in residential buildings under different pump energy retrofitting scenarios a detailed representation of the Swiss power heating system. The sensitivity PV storage deployment, including lithium-ion (LiB) vanadium redox flow batteries (VRFB), with respect distribution network capacity is also investigated. We propose an open-source dispatch sector coupling model (GRIMSEL-AH) minimise system...
Deep energy retrofit across the European building stock would require decades during which boundary conditions will change. This study identifies a range of pathways, using dynamic model, bottom-up model and an optimization for different climate scenarios. We consider 1.1 million options in Swiss residential economic/environmental objectives until 2060. Despite replacement old by new buildings, demand greenhouse gas (GHG) emissions reference scenario without deep retrofitting are likely to...
GaAs nanowires were heated locally under ambient air conditions by a focused laser beam which led to oxidation and formation of crystalline arsenic on the nanowire surface. Atomic force microscopy, photoluminescence Raman spectroscopy experiments performed same single in order correlate their structural optical properties. We show that local changes act as barrier for thermal transport is interest thermoelectric applications.
Semiconductor nanowires are nanoscale structures holding promise in many fields such as optoelectronics, quantum computing, and thermoelectrics. Nanowires usually grown vertically on (111)-oriented substrates, while (100) is the standard semiconductor technology. The ability to grow control impurity doping of ⟨100⟩ crucial for integration. Here, we discuss single-crystalline nanowires, structural optoelectronic properties p-n junctions based InP nanowires. We describe a novel approach...
