New Publication: Improving Quantum Well Tube Homogeneity Using Strained Nanowire Heterostructures

Group PhD student Nikesh Patel has just had his first paper accepted in ACS Applied Materials and Interfaces. His study uses a new methodology to understand how quantum "shells" - less than 10nm thick - vary both within single nanowires, and between them. By using automated high-throughput approaches on over

New Paper: Defect-Free Axially Stacked GaAs/GaAsP Nanowire Quantum Dots with Strong Carrier Confinement

In a new collaboration between Yunyan Zhang and Profs. Huiyun Liu (UCL), Ana Sanchez (Warwick) and David Mowbray (Sheffield) we report the fabrication and measurement of a GaAs/GaAsP quantum dot-in-wire structure in Nano Letters. While many material architechtures have been explored for single photon emission, the GaAsP-GaAs system provides

Group Seminar: Aruni Fonseka, Warwick Electron Microscopy

Dr Aruni Foseka of the Warwick Electron Microscopy Centre gave a seminar to the group and colleagues at the Photon Science Institute. Her talk covered electron microscopy techniques for nanomaterial characterisation, including dark-field and spectroscopic approaches.
