An original in situ cleaver for low temperature surface experiments

A simple, original and easy to construct, in situ crystal cleaver is presented. It is mounted directly on the sample holder and is particularly suitable for low temperature experiments. It is small enough to be adaptable on any low temperature x, y, z, Θ, φ manipulator. Cleaving in situ allows one to obtain a uniform and well-constructed single crystal surface. Adsorption experiments of krypton monolayers on an MgO (100) in situ cleaved crystal at 44 K are presented.
