  • 15Dec

    Prof Mark Blamire would like to invite you all to the Departmental Meeting on Friday 15th December 2017 at 10am, in Goldsmiths’ Lecture Theatre 1. This is a meeting aimed primarily at Assistant and Support Staff. Dr Rachel Evans will give a presentation about her research.  Please come along and hear about the highlights of the year. 

  • 14Dec

    Dr Amir Shirzadi, Visiting Research Scientist in Rolls Royce UTC and Senior Lecturer at The Open University. 

    The presentation will outline the new joining methods developed by Dr Amir Shirzadi and their applications in jet engines, satellite systems, electric cars and nuclear power-plants sectors. Exemplary components will be available for viewing

  • 12Dec

    Tickets cost £10 (this is a subsidised price thanks to many Department research groups) and will be available from the Servery. The number will be capped at 90, so it's advisable to buy early. Please retain the ticket - not only to get in, but also because purchase gives free entry to the Xmas raffle (which will be based on the ticket number).

    Music provided by Steve Watts (DJ) and Garance with her Jazz band, buffet meal, cash bar. Guests welcome.

  • 06Dec

    Speaker: Bhasi Nair. All welcome.

    Starting: 1.15pm (25 mins + 5 mins questions)

    Seminar by Professor E. Towe, Carnegie Mellon University, Pittsburgh, PA 15213

    Abstract: Synthesis of semiconductor thin films by molecular beam epitaxy has enabled the creation of artificial heterostructures with unique engineered properties for fundamental investigations as well as practical applications in electronic and photonic devices.  This presentation will discuss use of liquid-metal-enabled molecular beam epitaxy for III-nitride compound semiconductor films; we illustrate how this semiconductor alloy system can be used as a vehicle for illustrating basic concepts in practical quantum nanostructure engineering.  We then discuss a new class of two-dimensional semiconductors¾the transition-metal dichalcogenides¾that potentially offer new paradigms for device architectures.  Finally, we give examples of how semiconductor nanostructures are transitioned into practical technologies.

    All welcome.

    Dr Zhun-Yong Ong from the Institute of High Performance Computing Singapore will be giving a Materials Modelling Seminar.  All are welcome to attend.

    Abstract:
    The diffusion of heat across the boundary between two insulating crystalline solids is controlled by its Kapitsa (thermal) resistance, which is determined at the microscopic level by the reflection and transmission of quantised lattice vibrations (i.e. phonons), and depends strongly on the crystallographic microstructure of the interface. However, our conceptualisation of phonon scattering by the interface relies heavily on analogies from wave optics and acoustics, and remains limited by the lack of computationally efficient methods  or quantifying the transmission and reflection of individual phonons, constraining our ability to analyse the theoretical connection between phonon scattering and interfacial microstructure. 

    In this talk, I discuss how these difficulties can be overcome by extending the Atomistic Green's Function method that is commonly used to study ballistic phonon transport. I first show how the Kapitsa resistance phenomenon can be treated as a scattering (S-matrix)  roblem within the familiar conceptual framework of conventional quantum  mechanics. This approach allows us to employ existing theoretical machinery, originally developed for studying quantum transport in open systems, as the basis for our extension of the Atomistic Green's Function (AGF) method.Our extension of the AGF method enables the precise calculation of transition amplitudes between phonon channels (i.e. the individual elements of the S-matrix) and yields insights into the dependence of the transmission and reflection  oefficients on interfacial microstructure as well as phonon frequency, momentum and polarisation. Other possible applications of our extended AGF approach include the lattice defect and edge scattering of phonons. To illustrate the utility of this method, we present some  imulation results and analysis, obtained using inputs from ab initio calculations, for the MoS2/WS2 interface and isotopically non-uniform graphene. The concepts and numerical techniques developed in our approach may be potentially useful for analogous scattering  roblems in other areas such as tight-binding models, photonics and acoustics.

  • 20Nov

    Professor Lars Öhrström from Chalmers Tekniska Högskola & Berkeley Global Science Institute

    Metal-organic frameworks are coming of age. Numerous potential applications are seriously investigated by industry and a few products are already on the market. This talk will trace some of their origin, from the 1916 Japanese invention of the term coordination polymer to the molecule-based magnetic materials of the early 1990’s. I will also describe how network topology analysis is applied to different fields of solid-state chemistry, especially MOFs but also group 14 allotropes and related compounds, ice polymorphs, zeolites, supramolecular (organic) solid-state chemistry, Zintl phases, and cathode materials for Li-ion batteries.[1] Recent IUPAC recommendations and ongoing work on the terminology and nomenclature of MOFs will also be discussed.[2] Finally I will mention how metal−organic frameworks challenge our perceptions about the properties of crystalline materials.[3]

  • 16Nov

    The first Quiz of the year will be held on 16th Nov, starting at 1pm (and lasting just under an hour). Paulina Librizzi will be the Quizmaster. Registration will be open from Monday morning. The cost is £2 per person, which covers nibbles, as well as entry to the Quiz. Teams comprise between 4 and 6 people. One person should pay for the whole team and register its name at the Servery. The deadline for registration is the morning of Wed. 15th (or earlier if the limit of 12 teams has been reached, which is quite likely). As usual, there will be cash prizes for the top two teams.

    Kieren Lovell from University Information Services 

    This lecture is in the postgraduate student timetable, but it is available to everyone in the Department, so please do come along if you are interested. There have been a number of high profile cyber-attacks this year on organisational infrastructure, and there are regular reports in the media about banking fraud and theft of personal data, so it is worth finding out how this might affect you and what you can do to reduce the risks.
