Figure 4: Thermal resonance frequency response of the CCNT at varying compression conditions. The z-piezo scan size was set at 2500 nm for the (b) primary and (a) secondary resonance modes at the following extent of compression: (i) 125, (ii) 250, (iii) 375, (iv) 500, (v) 750, and (vi) 875 nm are presented. The occurrence of slip stick is observed beginning at a compression distance of approximately 457 nm and can be observed at larger compression distances.
