Biography
Dr Alexandre Cuenat is the lead scientist for Nanomaterials at NPL. He holds an Engineering Degree, an MSc and a PhD in Physics all from the Swiss Federal Institute of Technology (EPFL). His main interests is energy transfer at the nanoscale.

His PhD research elucidated the kinetics of intermetallic amorphous clusters formation during ion implantation. His time was split between experiments using the ion implanter, Channeling-Rutherford Backscattering Spectrometry (RBS) and Transmission Electron Microscopy (TEM) and theoretical modelling by Molecular Dynamics or kinetic rate theory. He was also teaching advance physics to material scientists and laboratory physics for students in electrical engineering and micro-engineering.
He then joined the Applied Physics group at Harvard University as a Postdoctoral Fellow. He worked with Prof. Mike Aziz on the kinetics of atomic rearrangements that underlie most of modern processing techniques. He developed a UHV system to study in-situ and in real time the self-organization of nanoscale structures on semiconductor surfaces using UV-light scattering spectroscopy. In conjunction with atomic force microscopy, his system allowed to demonstrate that lateral templating can effectively guide self-organized patterns. This effect can be useful for hierarchical mass production of nanoscale 2D and 3D architectures and provide an excellent basis for testing and further development of driven systems.
He came back to Europe as a member of the SiGeNet network (SiGeC nanostructures: a new path to silicon based optoelectronics) and worked on molecular beam epitaxy of SiGe quantum dots and their alignment using focused ion beam pre-patterned substrates.
Since 2004 he is a permanent member of staff at NPL, where his group works on nanomaterials 3D characterization and transport in nanostrucutred materials using scanning probe techniques.
