The Martensitic Transformation in Silicon III. Comparison with Other Work

Abstract In the previous papers [P. Pirouz, R. Chaim, U. Dahmen and K.H. Westmacott, Acta metall. mater.38, 313 (1990); U. Dahmen, K.H. Westmacott, P. Pirouz and R. Chaim, Acta metall. mater.38, 323 (1990)] the experimental observations on the cubic→hexagonal phase transformation in silicon were presented and a crystallographic analysis was given which explained this transformation on the basis of lattice accommodation in twin-twin interactions or propagation of secondary twins into the matrix. In the present paper, the martensitic nature of the transformation is discussed and other recent observations of hexagonal silicon in ion-implanted material, heat treated Czochralski Si, and silicon deformed under hydrostatic pressure are considered in the light of the present work.
