An interesting setup for on-chip nanomechanical resonators is that of coupling them to electrical microwave cavities for detection and manipulation. Here we show how to achieve a large cavity coupling energy of up to (2 \\pi) 1 MHz/nm for metallic beam resonators at tens of MHz. We used focused ion beam (FIB) cutting to produce uniform slits down to 10 nm, separating patterned resonators from their gate elec","authors_text":"Andrew Fefferman, Jaakko Sulkko, Jeevak Parpia, Lorenz Lechner, Meri Helle, Mika A.
