Alexandra Ramadan

Postdoctoral Research Assistant

I am a postdoctoral research assistant working on lead based perovskite materials for photovoltaic applications in the group of Professor Henry Snaith in the Department of Physics. My research focus is on using surface science/materials characterisation techniques to understand the electronic and physical structure of these materials. Prior to this I carried out my doctoral research in the Centre for Plastic Electronics at Imperial College London receiving my PhD in late 2015.

I am interested in thin film growth of lead based perovskite materials and organic semiconductors for photovoltaic applications. I am an expert in the growth of inorganic and organic thin films using organic molecular beam deposition (OMBD) in high (HV) and ultra-high (UHV) vacuum.

A large focus of my work is on characterisation of thin films and interfaces and I am particularly interested in using the following surface science techniques to understand these materials systems: STM (Scanning Tunneling Microscopy), LEED (Low Energy Electron Diffraction), LEIS (Low Energy Ion Scattering) and UPS (Ultra-Violet Photoemission Spectroscopy). Characterisation of thin films are also carried out ex-situ of the growth environment using X-Ray diffraction, scanning electron microscopy (SEM), Atomic Force Microscopy (AFM) and transmission electron microscopy (TEM).
