Examining SrFe$_{2}$As$_{2}$ with a Low Temperature Scanning Tunneling Microscope

The new pnictide superconductors have generated huge excitement. These materials are the first to add some chemical diversity to the limited high-Tc list previously exclusive to cuprates. We examine the pnictide material parent compound SrFe$_{2}$As$_{2}$ with a low-temperature ultra-high vacuum scanning tunneling microscope (STM) at 4 K. We find multiple types of topography and spectroscopy with low energy features. We relate our data to results from ARPES and other experiments.
