Abstract:The trapped ions confined in a surface-electrode trap (SET) could be free from rf heating if they stay at the rf potential null of the potential well. We report our effort to compensate three-dimensionally for the micromotion of a single $^{40}$Ca$^{+}$ ion near the rf potential null, which largely suppresses the ion's heating and thus helps to achieve the cooling of the ion down to $3.4$ mK, which is very close to the Doppler limit. This is the prerequisite of the sideband cooling in our SET.
