Abstract
Optomechanical actuation was achieved reversibly using highly oriented pyrolytic graphite intercalated with bromine (1.9 mol% Br2). White light from a 150 W tungsten-halogen lamp was used for optomechanical switching. The displacement was approximately 4 micrometers and occurred only along the c-axis of the graphite. The rise and fall times were approximately 15 s. The origin of the optomechanical effect is the reversible exfoliation of the near surface region of the intercalated graphite.
