We present an electrostatically defined few-electron double quantum dot (QD) realized in a molecular beam epitaxially grown Si/SiGe heterostructure. Transport and charge spectroscopy with an additional QD as well as pulsed-gate measurements are demonstrated. We discuss technological challenges specific to silicon-based heterostructures and the effect of a comparably large effective electron mass ...
