Abstract

The theory developed by Coulson, Rushbrooke and Longuet-Higgins (CRLH) on the electron-charge density and the atom-bond polarisability in hetero-atom conjugated systems is used to show that n-electron charge transfer by Sn substitutional incorporation in aC:H would promote the tetrahedral structure. An agreement with Phillips stability criterion is found.The effective medium theory is then applied for predictions on the dielectric properties of narrow optical band-gap (0,6–1,5 eV) C-Sn alloys. It is suggested that the incorporation of electronegativeelements (F, Cl) would reduce the high sub-bandgap absorption.
