The electrical conductivity of a crystal was unexpectedly - TopicsExpress



          

The electrical conductivity of a crystal was unexpectedly increased by 400% when a sample of strontium titanate was left out for a day. Better yet, the increased conductivity lasted for several days. The phenomenon, dubbed persistent photoconductivity is different from superconductivity, but far more convenient since it occurs at room temperature. Its discovery could lead to advances in crystal-based computer memory technologies. And now we know why every science fiction movie that shows an advanced alien computer always depicts crystals bathed in light. Once again, life imitates art.
