  Engineered substrates offer a promising avenue towards graphene devices
having tunable properties. In particular, topographically patterned substrates
can expose unique behavior due to their ability to induce local variations in
strain and electrostatic doping. However, to explore the range of possible
science and applications, it is important to create topographic substrates
which both have tunable features and are suitable for transport measurements.
In this Letter we describe the fabrication of tunable, topographically
patterned substrates suitable for transport measurements. We report both
optical and transport measurements of graphene devices fabricated on these
substrates, and demonstrate characteristic strain and local doping behavior
induced by the topographic features.
