A HRTEM Study of Cronstedtite: Determination of Polytypes and Layer Polarity in Trioctahedral 1:1 Phyllosilicates
Cronstedtite HRTEM Layer Polarity Morphology Polytype Stacking Disorder Trioctahedral 1:1 Phyllosilicates
2011/12/5
Abstract: It is shown that polytypes or stacking sequences of cronstedtite, an Fe-bearing trioctahedral 1:1 phyllosilicate, can be determined using near-atomic high-resolution transmission electron mi...
Refinement of the Crystal Structure of Cronstedtite-1T
Cronstedtite Layer Silicate Order-Disorder (OD) Polytypism X-ray Diffraction
2011/12/6
Abstract: The crystal structure of cronstedtite-1T was refined in space group P31m, using two crystals: a triangular tabular crystal from Herja, Romania and a conical crystal from Lostwithiel, Cornwal...

Bandstructure Cronstedtite Density of states Electronic structure Extended Huckel method
2011/12/1
Abstract: The bonding in a cronstedtite layer was studied using a ninefold ordered supercell band structure calculation. The tight-binding scheme based upon the extended Hückel method was used to pred...
