A Simple Numerical Calculation Correctly Predicts the Observed Size Regime for Growth of Tetrapodal Chalcogenide Nanocrystals

摘要

The synthesis of materials with critical dimensions of the order of nanometers is at present an area of intense research.Studies of chalcogenide systems,such as CdSe which can exist in hexagonal (wurtzitic)or cubic (spharelitic)forms as well as polytypical phases,dominate much of this work.
