Atomic Resolution Observation of Calcite by SPM-8100FM

Introduction

Calcite is a calcium carbonate mineral which commonly found in the natural world and living organisms and has important functions in the ecosystem. For example, the phenomenon of biomineralization, by which living organisms precipitate inorganic minerals such as calcium carbonate, may possibly lead to synthesis of environment-friendly materials and has also attracted attention in the field of biomimetics. Observation of the crystal structure of calcite with atomic resolution provides clues for elucidation of the mechanism and process of biomineralization. Fig. 1 shows a calcite crystal sample collected from the natural world.
