Active feedback cooling is an important technique for achieving the quantum ground state in micro/nanomechanical resonators. We studied the effect of tensile strain on the achievable minimum temperature and quantum occupation number by fabricating a doubly clamped beam resonator from a GaAs/InAlAs strained layer heterostructure. Despite the increase of the minimum temperature, we demonstrate that the occupation number can be decreased by applying tensile strain to the mechanical resonator.
