Semiconducting higher manganese silicides (HMS) with a composition near that of MnSi are of special 1.7 interest due to their thermoelectric properties. We report on the growth of HMS layers deposited by MBE using the template technique. In particular the influence of the template thickness on the s

โฆ Synopsis
This study reports on transmission electron microscopy investigations of higher manganese silicide (HMS) layers grown by molecular beam epitaxy (MBE) on (001)Si using the surfactant mediated reactive deposition technique. Applying Sb as a surfactant (surface active substances) results in an increased silicide island density as well as in a change in the crystalline orientation of the silicide islands. The silicide islands were found to grow into the Si matrix. The preferential epitaxial relationship was determined to be (100)[010]Mn Si uu

We report on the growth of thin titanium silicide layers on Si(001) by surfactant-mediated reactive deposition (SMRD) at temperatures in the range of 300-800 8C. The surface diffusion of Ti and Si is crucial for the morphology of the growing silicide layer and can be altered by the presence of a sur
The most rich silicon silicides of manganese, the group of higher manganese silicides (HMS), have the composition MnSi x with x in the range from 1.67 to 1.75. This material group with a tetragonal crystal structure shows semiconducting electronic properties, with promising application in thermoelec
