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.

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. By quickly sorting

Photon 2018

Both Stefan and Arturo will present at Photon 2018 in Aston, UK (September 3rd-6th, 2018). Stefan presented a poster on “Time and Spectrally-Resolved Microscopy of GaAsP-GaAs core-shell Quantum Well Lasers“, describing some recent work with collaborators in the group of Prof. Huiyun Liu at University College London. Arturo presented a

UK III-V Nanowire Meeting

Patrick spoke at the UK III-V nanowire meeting in Oxford on March 20th on “Big-data for nano-wires”. This meeting brought together the UK community in nanowire growth and characterisation for a one-day workshop. PhD student Arturo gave a poster on his most recent work related to nanowire statistics.

Thanks to Arturo for some illustrative laser path photos in the newly set-up lab space

New Publication - Large-scale statistics for threshold optimization of optically pumped nanowire lasers

Arturo’s recent work has been published in Nano Letters [at http://pubs.acs.org/doi/10.1021/acs.nanolett.7b01725 ]. This work was done in collaboration with the group of Professor Chennupati Jagadish at the Australian National University. In this paper, we describe how automated and high-speed spectroscopy can

Arturo speaks at Nanowire week 2017

Arturo spoke at Nanowire week 2017 in Lund, Sweden today. In his first talk at an international conference, he presented his recent work on “Large-scale statistics for threshold optimization of optically pumped nanowire lasers” to a large audience of nanowire growth and characterisation experts from around the world.

The group goes to Oxford

Arturo, Xiaoyan, Stefan and Patrick visited Oxford for the UK III-V Nanowire workshop hosted at Corpus Christi College. While Arturo presented a poster and Patrick a talk, the whole group got to meet the ever increasing number of researchers working on III-V Nanowires in the UK.

Arturo passes 1st year viva

Congratulations to Arturo, who has passed his 1st year viva and now continues into the PhD program. His project will focus on the understanding of inhomogeneity in nanowire lasers, and their development towards device-implementable nanomaterial.

Lab Progress - first data

After an extended ~ 3month move period, the micro-PL system is back up and running with our new laser system. Just in time for Arturo to get started on his new project…!
