![]() The research focuses on commercially available polyaromatic molecules, such as phthalocyanines and perylene derivatives. Their semiconducting character is due to the presence of delocalised π-orbitals, more often C-C double bonds, which leads to a lowering of the bandgap. Molecular materials offer attractive alternatives to inorganics for optoelectronic applications, due to their low cost, low weight and the possibility to modify their properties easily through the insertion of functional groups by chemical synthesis. Professor Sandrine Heutz’s group is developing capability in the growth and characterisation of molecular thin films. We have compiled a list of microwave dielectric resonator materials and their properties. The electric field controls the polarisation, the magnetic field controls the magnetisation and the stress controls the strain. Recent research into functional materials has been towards combining two or more of these into what is now known as multiferroic materials so for example, a piezolectric “buzzer” is caused by the application of an AC voltage to a piezoelectric material causing it to vibrate. Ferromagnetic materials are used in magnetic storage devices. These are materials such as piezoelectrics where the application of a voltage causes a change in dimensions, or ferroelectrics where the application of a voltage causes a change in the relative permittivity. This group is headed by Professor Neil Alford MBE FREng and the main emphasis is on functional oxides. The thin film activity in the Department of Materials takes place in two groups: Physical Electronics and Thin Film Materials Functional materials are also of critical importance in materials for energy such as electro- and magnetocaloric materials, for energy storage and for solar harvesting functions. Functional materials are often used in electromagnetic applications from KHz to THz and at optical frequencies where the plasmonic properties of metals assume particular importance. Fully funded Departmental PhD projects (including DTP)įunctional materials are generally characterised as those materials which possess particular native properties and functions of their own. For example, ferroelectricity, piezoelectricity, magnetism or energy storage functions.įunctional materials are found in all classes of materials: ceramics, metals, polymers and organic molecules.Information for Materials' PhD Students.MSc in Advanced Materials Science and Engineering.Why study Materials Science at Imperial?.What is the Undergraduate Research Opportunity Programme?.Student Office and Student Support Staff.This has included the invention of experimental materials that stimulate bone repair, the examination of the future of compression garments, the development of clothing-based wearable computing, and a collaboration with the Royal Centre for Defence Medicine and other industry partners to develop affordable, realistic, and anatomically correct simulators for clinical training environments.Search Imperial Search Department of Materials Section Navigation Promoting health, addressing the social determinants of health, and developing successful interventions to address a range of pressing medical and health-related problems.
