Interesting relationships have been found between the electron density parameter, average bond length, homopolar energy gap, heteropolar energy gap, ionicity, bulk modulus and microhardness for binary tetrahedral semiconductors. The estimated values of these parameters are in good agreement with the available experimental values and theoretical findings. The electron density parameter data are the only input data to estimate all the above properties.

Keywords: Electron density parameter; bond ionicity; bulk modulus; microhardness; compound semiconductors
