Summary
Ultra-Porous Devices by Synergistic Aerosol and Atomic Layer Depositions. The project aspires to develop a scalable low-cost approach for the synthesis and integration of ultra-porous films in nanodevices. The project intends to deposit atomic layers onto aerogel-like nanoparticle networks, self-assembled by thermophoresis of flame-made aerosols. This would increase the atomically-deposited layer mass by several hundred-fold per cycle and result in ultra-porous films with electrochemically activ ....Ultra-Porous Devices by Synergistic Aerosol and Atomic Layer Depositions. The project aspires to develop a scalable low-cost approach for the synthesis and integration of ultra-porous films in nanodevices. The project intends to deposit atomic layers onto aerogel-like nanoparticle networks, self-assembled by thermophoresis of flame-made aerosols. This would increase the atomically-deposited layer mass by several hundred-fold per cycle and result in ultra-porous films with electrochemically active surface areas. It is intended that the project will demonstrate the fabrication of solid–gas, solid–liquid and solid–solid nanointerfaces, which will be applicable to key emerging technologies such as wearable medical diagnostics.Read moreRead less
III-V semiconductor nanowire solar cells without p-n junctions. This project proposes a new class of nanowire solar cells that do not rely on conventional electrical (p-n) junction for photo-generated charge carrier separation.

This approach is expected to fundamentally change the design of solar cells, eliminating the technologically challenging need for formi ....III-V semiconductor nanowire solar cells without p-n junctions. This project proposes a new class of nanowire solar cells that do not rely on conventional electrical (p-n) junction for photo-generated charge carrier separation. Instead the band structure of the semiconductors is engineered to form a misalignment which leads to the spatial separation of carriers. This approach is expected to fundamentally change the design of solar cells, eliminating the technologically challenging need for forming good electrical junctions, while retaining all advantages inherent to III-V semiconductor nanowire solar cells. More importantly, the device concept proposed is expected to have implications for a wider class of solar cells based on exotic/novel materials or nanostructures where achieving both n- and p-doping may be challenging.Read moreRead less
