Two closely coupled CECAM Workshops on the use of empirical methods for semiconductor nanostructure design and modelling will be held in Dublin and Manchester. The first ACAM Workshop (Dublin) focuses primarily on computational/technical issues, numerical implementations and parametrisation strategies, followed immediately by the second STFC Daresbury Workshop (Manchester) highlighting the scientific issues and demands related to empirical nanostructure design and modelling.
A variety of modelling implementations [k.p, tight-binding, valence force field, empirical pseudopotential, etc.] are being employed that exploit not just the accumulated knowledge of existing experimental and ab-initio results, but also exploit the increased computational power and advanced computational methods now available. The development of empirical methods inherently facilitates synergy between experiment and theory. Proper implementations of empirical methods are capable of delivering new levels of understanding and design for both materials and devices alike. Applications of such schemes span from designing emitters and absorbers used in conventional optoelectronics, through new architectures proposed in quantum information processing, to investigation of novel concepts for the design of future high efficiency solar cells. The workshops address all of these topics and are of relevance both to theoretical and experimental researchers.

Detailed Workshop Description
Theory, modelling, and computational methods for semiconductor materials and nanostructures are topics of rapid growth and great international interest. A lot of the world-wide effort over the past 50 years in establishing the theoretical foundation of methodologies for calculations of structural, electronic, optical and transport (electrical and thermal) properties of semiconductor nanostructured materials [1-61] are now coming to fruition [62-67].
Modern crystal-growth techniques, such as molecular beam epitaxy (MBE) or metalorganic chemical-vapour deposition (MOCVD), are capable of producing prescribed crystal structures, sometimes even in defiance of equilibrium bulk thermodynamics.
To correlate desired electronic and optical properties with the structure cannot be efficiently done experimentally solely by trial-and-error methods. Hence computational methods and novel algorithms that combine fast empirical solvers, detailed knowledge of the nanostructure shape and size, chemical composition, and mechanical properties, together with ever increasing computational power available are required to address this fundamental problem.
Among the many empirical methods available, the multi-band k.p (k.p), empirical tight binding (ETB), and empirical pseudopotential (EPM) methods are proving invaluable in the design and modelling of modern optoelectronic devices and semiconductor nanostructures.
