Phonons 2001 Logo

Spacer The logo shows a simulated slow transverse (ST) phonon image for 45 degree twist-bonded (001) GaAs. In twist bonding, the two wafer pieces are rotated 45 degrees around (001) before being brought into contact for bonding. The computer generated image uses a simple acoustic mismatch model to predict the flux of ST phonons which scatter into new ST modes at the solid-solid interface. The angular width from the center of the image to one edge is approximately 38 degrees. (M.E. Msall, prepublication)
