Graduation Congratulations to first group PhD student Juan (Arturo), who managed to graduate today. Having passed his viva in March 2020, it was a long wait to return to Manchester. He is now working with Synaptec in Glasgow.
PhD Viva: Arturo Arturo Alanis (the first PhD student of the group) had a successful PhD viva today. His thesis examiners were Dr Hannah Joyce (Cambridge) and Dr Jessica Boland (Manchester). Arturo has already secured a postdoctoral position to start in a few weeks; we’ll be sad to see him go, but
New Paper: Characterisation, Selection and Micro-Assembly of Nanowire Laser Systems Our collaborative work on the selection, transfer and testing of semiconductor nanowire lasers has now been published in Nano Letters. In this work, growth colleagues at ANU prepared nanowire lasers which were characterised at Manchester. This characterisation was used to select bins of nanowires, which were transferred using a cutting
New arXiv paper - Characterisation, Selection and Micro-Assembly of Nanowire Laser Systems Our new paper produce in collaboration with Michael Strain and Antonio Hurtado (University of Strathclyde) and the Jagadish group (Australian National University) is now available on the arXiv. In this work, we combine high-quality nanolaser growth (ANU) with high-throughput optical spectroscopy (Manchester) and high-speed pick-and-place technology (Strathclyde) to demonstrate scaled-up
Conference Talk: Arturo at MRS Fall Group PhD student Arturo has given a talk at MRS Fall 2019 in Boston. He spoke on “Nanolaser Optimization through Statistical Optoelectronic Analysis“.
New Paper - Threshold reduction and yield improvement of semiconductor nanowire lasers via processing-related end-facet optimization Arturo has had a paper accepted for publication in Nanoscale Advances, describing the impact of the transfer process on the morphology and threshold of semiconductor nanowire lasers. While many studies have sought to improve the threshold for lasing in semiconductor nanowire lasers, the role of process has not been significantly
New Paper - Visible and infrared photocurrent enhancement in a graphene-silicon Schottky photodetector through surface-states and electric field engin Nawapong Unsuree has had a paper accepted for publication in 2D Materials. coming from a collaboration between the Echtermeyer group (Manchester) and the Parkinson group. The research was conducted in the National Graphene Institute and the Photon Science Institute. This new research reports the application of infrared scanning photocurrent microscopy
New Paper - Emission Properties and Ultrafast Carrier Dynamics of CsPbCl3 Perovskite Nanocrystals Congratulations to Ruben Ahumada-Lazo for his new paper on emission properties of perovskite nanocrystals. In his new paper, published in ACS Journal of Physical Chemistry C, he used ultrafast and high-fluence optical techniques based at the Photon Science Institute to reveal the radiative and non-radiative recombination pathways in CsPbCl3 perovskite
Project Summary: Large-scale approaches for nanolaser optimization The emission of light at the nanoscale is of great importance for information processing, medicine and fabrication for optical circuits. Optical circuits would improve processing speeds and decrease the energy consumption necessary to operate data centres. This is due to the manipulation of light which can carry more information at
New Paper - Optical Study of p-Doping in GaAs Nanowires for Low-Threshold and High-Yield Lasing Our new work on large-scale statistical spectroscopy to optimize nanowire lasers is published today in Nano Letters. In this work, PhD student Arturo studied thousands of nanowires to identify the lowest threshold nanowire, as well as to model emission to identify the primary sources of non-radiative emission.
