  For instance, University of Arkansas professors Huaxiang Fu and Laurent Bellaiche recently reported simulation results showing that 5-nanometer ferroelectric quantum dots created small magnetic vortexes that could be "unraveled" to represent bits.

  Separately, University of Arkansas professors Huaxiang Fu and Laurent Bellaiche recently reported simulation results that indicate individual nano-scale ferroelectric devices can also be harnessed reliably as semiconductor memories.
  
  "Ferroelectricity is caused by atomic off-center displacements resulting from a delicate balance between short-range covalent and long-range Coulomb interactions.Consequently, many researchers speculated that the effect would disappear at the nanoscale," said Bellaiche."But our results show that large, robust off-center displacements exist in quantum dots as small as 5 nanometers."
  
  Bulk ferroelectric materials spontaneously form into nanoscale dipoles, enabling them to transduce electricity.However, Bellaiche said, many doubted that such materials would retain their ferroelectric properties at the nanoscale.To find out, Fu and Bellaiche examined barium titanium oxide in 5-nm-diameter nanoparticles (called quantum dots because of the predominance of quantum confinement effects in particles so small).
  
  They found the ferroelectric transducing effect still present at 5 nm, albeit in slightly less efficient form.Instead of forming long chains, Fu and Bellaiche said, the nanoscale ferroelectric forms into small magnetic vortexes.However, by applying a magnetic field, Fu and Bellaiche were able to "unravel" the vortexes and achieve performance comparable to that of bulk ferroelectrics.

  By "compressing" or straining the semiconductor Scandium nitride (ScN) at the atomic level, University of Arkansas physicist Vivek Ranjan, Laurent Bellaiche, associate professor of physics and Eric J. Walter, College of William and Mary, showed that the material goes through optical changes that take it through the visible spectrum.

  Physics professor Laurent Bellaiche, at UA since 1999, was named on June 26 to his position as Twenty-First Century Endowed Professorship in Nanotechnology and Science Education.
  
  His primary interests are the prediction, design and optimization of properties of semiconductors and ferroelectric materials, research that he believes will lead to smart cards with more storage, ultrasound machines with sharper resolutions and sonar-listening devices that can scan greater distances.
  
  Bellaiche said the endowed professorship will provide him about $ 20, 000 a year for his work.
  
  "It gives us a lot of freedom to do research," he said.
