Soap, DNA and semiconductors
December 13, 2000How can studying soap lead to better methods for transporting drugs around the body? Where’s the link between semiconductors and DNA and how can statistical physics reveal how ecosystems evolve? Find out at the Institute of Physics Condensed Matter and Materials Physics (CMMP) Conference being held at the University of Bristol between 18 and 21 December 2000. The four-day conference will host presentations covering a wide range of issues including brittle metals in rail tracks and quantum computing.
The CMMP Conference is organised by the Condensed Matter and Materials Physics Division of the Institute of Physics. It contains thirty different symposia including ‘Plasma and Ion Beam Methods and Applications’, and ‘Helium Physics’. As well as the symposia there is a special session entitled ‘Physics at the Biology Interface’, with a number of talks including one on a silicon, array-based, artificial nose.
There will also be seven prize and plenary lectures from world-renowned researchers. Topics include ‘Stripes, Spots and Helter-Skelters – New States in Quantum Hall Systems’, by J T Chalker at Oxford University, and ‘Principles and Applications of Coherent Hard X-ray Imaging’, by a group of researchers at CERN, the European Organisation for Nuclear Research, and the Centre National de Recherche Scientifique, (CNRS).
The other sessions at the conference are ‘Artificial Structures’, ‘Complex Fluids’, ‘Computational Physics’, ‘Electronic Structure’, ‘Ferroelectrics’, ‘High-Temperature Superconductivity’, ‘Low Temperature Physics’, ‘Low Dimensional Magnetism’, ‘Magnetic Thin Films’ , ‘Multilayers and Spin Values’, ‘Nanoscale Physics and Technology’, ‘Novel Non-cuprate Superconductivity’, ‘Orbital and Quadrupolar Effects in Magnetic Systems’, ‘Physics of Cold Metals’,
‘Physical Realisations of Quantum Computing’, ‘Polymer Crystallisation’, ‘Polymer Electroluminescence and Transport: the Role of Polymer Morphology’, ‘Reflectrometry from Magnets and Superconductors’, ‘Semiconductor Physics: Transport Properties’, ‘Semiconductors: Low Dimensional Semiconductors’, ‘Semiconductors: Characterisation and Devices’, ‘Semiconductor Physics: Optical Properties’, ‘Statistical Physics’, ‘Strongly Correlated and Mesoscopic Systems’, ‘Superconductivity Vortex Matter’, ‘Superconductivity: Materials and Devices’.

Semiconductor News and Current Semiconductor Events RSSBottoms up: Better organic semiconductors for printable electronics
Researchers from the National Institute of Standards and Technology (NIST) and Seoul National University (SNU) have learned how to tweak a new class of polymer-based semiconductors to better control the location and alignment of the components of the blend.
NIST studies how new helium ion microscope measures up
Just as test pilots push planes to explore their limits, researchers at the National Institute of Standards and Technology (NIST) are probing the newest microscope technology to further improve measurement accuracy at the nanoscale.
Scientists grow 'nanonets' able to snare added energy transfer
Using two abundant and relatively inexpensive elements, Boston College chemists have produced nanonets, a flexible webbing of nano-scale wires that multiplies surface area critical to improving the performance of the wires in electronics and energy applications.
'Racetrack' for fast electrons in semiconductor structures
In order to realize the electrical units of voltage, resistance and current with highest accuracy quantum effects in nano-circuits are nowadays used. Important prerequisites are extremely pure semiconductor layers where high-mobile electrons move through the crystal without collision with residual impurities.
Creating unconventional metals
The semiconductor silicon and the ferromagnet iron are the basis for much of mankind's technology, used in everything from computers to electric motors. In this week's issue of the journal Nature (August 21st) an international group of scientists, including academic and industrial researchers from the UK, USA and Lesotho, report that they have combined these elements with a small amount of another common metal, manganese, to create a new material which is neither a magnet nor an ordinary semiconductor.
Fast quantum computer building block created
The fastest quantum computer bit that exploits the main advantage of the qubit over the conventional bit has been demonstrated by researchers at University of Michigan, U.S. Naval Research Laboratory and the University of California at San Diego.
Light touch: Controlling the behavior of quantum dots
Researchers from the National Institute of Standards and Technology (NIST) and the Joint Quantum Institute (JQI), a collaborative center of the University of Maryland and NIST, have reported a new way to fine-tune the light coming from quantum dots by manipulating them with pairs of lasers.
New Speed Record for Magnetic Memories
Fast memory chips such as DRAMs and SRAMs (Dynamic and Static Random Access Memory) commonly used today have one decisive disadvantage: in case of power interruption, they lose their stored information.
Toward plastic spin transistors
University of Utah physicists successfully controlled an electrical current using the "spin" within electrons - a step toward building an organic "spin transistor": a plastic semiconductor switch for future ultrafast computers and electronics.
The shape of things to come
Instead of using a flat microchip as the light sensor for their new camera, a team of engineers has developed a sensor that is a flexible mesh of wire-connected pixels.
