Evolution of the ratio ν2(C-MCL)o2 with consecutive Co deposition times. (a) Evolution of the ratio ν2(C-MCL)o2 with a consecutive deposition time of 1.0 min. This ratio for the CPA-MCL (featuring transverse nano-strings) has a slope that is practically equal to its initial slope and is consistent with the increment in mass of the C-MCL. This slope for the coated CPE-MCL (longitudinal nano-strings) is smaller than the slope for the CPA-MCL: an increase in the value of its spring constant, ko, must have occurred because the increase in mass was the same for the two MCLs. (b) The same behaviour was observed for the other two simultaneously off-normal Co-coated micro-cantilevers with consecutive deposition times of 4.0 min.
