Dr Alexander Robson

ERDF Technology Access Consultant (Physics)

Research Overview

I am an ERDF Technology Access Consultant based in the Department of Physics, working on the Cumbria Innovations Platform (CUSP) project, a new initiative that helps Cumbrian SMEs to access technical and management expertise from Lancaster University and the University of Cumbria to accelerate innovation in new products and services.

In particular, my role facilitates engagements with the Department of Physics and the Quantum Technology Centre, allowing businesses to engage with world class facilities featuring state-of-the-art nanofabrication and measurement equipment.

Research Interests

· Cross-sectional analysis of materials via beam-exit cross-sectional polishing, a technique developed and patented by Lancaster University.

· Quantitative nanoscale mapping of materials via scanning probe microscopy, including nanomechanical and nanothermal properties.

· Nanoscale materials, structures and devices, 2D materials and their applications.

Background

Prior to my current appointment, I worked as a senior research associate on the European Commission project QUANTIHEAT (QUANTItative scanning probe microscopy techniques for HEAT transfer management in nanomaterials and nanodevices, FP&-NMP-2013-LARGE-7), which involved twenty partner institutes in academic and industrial fields. The QUANTIHEAT project aims to tackle issues relating to thermal metrology at the nanoscale and to deliver validated standards, methods and modelling tools.

Before joining the QUANTHEAT project, much of my research focused on the cross-sectional analysis of III-V compound semiconductor materials and devices via scanning probe microscopy and beam-exit cross-sectional polishing (BEXP), a technique developed at Lancaster University.

I have a PhD in Physics from Lancaster University, thesis title “Cross-Sectional Scanning Probe Microscopy of III-V Semiconductors” (Supervisor: Dr Manus Hayne).
