Group lunch
After over 18 months, we had a first “all-group” meeting and lunch in person. It’s been a long time, but great to all finally be back in the same place!

Conference Talks: EUROMAT 2021
Group PhD student Ruqaiya Al-Abri and postdoctoral researcher Stephen Church both gave oral talks at EUROMAT 2021. The conference, originally scheduled to be held in-person in Vienna, ran as a virtual meeting.
Ruqaiya gave her first oral presentation on her collaboration with Lund University on “High-throughput spectroscopy for optimizing internal
Invited Talk - SPIE Optics and Photonics 2021
Patrick gave a remote invited talk in the Low Dimensional Materials and Devices session of SPIE 2021, hybrid hosted in San Diego.
He spoke about “High-throughput spectroscopy of semiconductor nanowires in the presence of inhomogeneity“ including new material from group members.
New Lasers in the Photon Science Institute
The group have received and comissioned a new ultrafast laser system courtesy of an EPSRC World-Class Labs grant! The new system, a 20W PHAROS/ORPHEUS-HP can provide tunable 250fs laser pulses from 315nm to 16,000nm at pulse energies up to 10microjoules and repetition rates of 200kHz.
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
New Publication: Self-Catalyzed AlGaAs Nanowires and AlGaAs/GaAs Nanowire-Quantum Dots on Si Substrates
A new collaborative paper led by Giorgos Boros and the team of Xuezhe Yu and Huiyun Liu at University College London has been published in J Phys Chem C. In this work, Giorgos reported the development of high quality ternary nanowires (AlGaAs) grown via MBE. While the AlGaAs/GaAs heterostructure
PhD examiner for Arelo Tanoh
Patrick acted as external examiner for the PhD viva of Arelo Tanoh (a student in the Rao group at the University of Cambridge). Arelo defended his thesis, entited “LUMINESCENT HARNESSING OF 2D TRANSITION METAL DICHALCOGENIDE EXCITONS”.
Welcome to Andras Botar
The group will be joined for the next 8 weeks by a summer intern through the “Learning Through Research” program at Manchester. Andras will work on big-data methods for handling, sharing and processing large spectral and imaging datasets produced in the group.
Welcome Andras!
New Conference Proceeding: Effect of Micron-scale Photoluminescence Variation on Droop Measurements in InGaN/GaN Quantum Wells
Rachel Barrett (a PhD student in the Binks group in Manchester) has had a conference proceeding published in collaboration with the OMS group. The study, on micro-scale spectroscopy of GaN-based quantum wells was presented at Photon 2020 and was carried out in collaboration with the Department of Materials Science at
Invited Talk - Compound Semiconductor Week 2021
Patrick gave an invited talk at a virtual Compound Semiconductor Week 2021 (nominally in Stockholm) on “A needle in a needlestack – exploiting functional inhomogeneity as a tool for optimized nanooptoelectronics“. This opened the B2 session “Nanowire growth and characterization“.
