“…The surge of current at t = 2.1 s is probably caused by changing the type of strain of CNTs from bending-strain to stress-strain under the action of adhesion forces holding the CNT on top of the AFM probe during retraction at the initial instant of time [ 27 ]. Thus, when bending the CNT, stretching strain with a positive charge arises on one side of the top of the nanotube, and compressive strain with a negative charge occurs on the other, reducing the total piezoelectric charge [ 4 , 28 ]. With the subsequent stretching of the nanotube, a positive piezoelectric charge begins to predominate at its top, which results in the detection of a small increase in current.…”

“…The positive potential was observed at the tops of the CNT bundles up to 130 nm in diameter, which also corresponded to a bundle of 2–3 nanotubes. The negative potential was formed at the tops of the large diameter bundles, which may be due to the prevalence of bending strain in nanotubes when the diameter of the bundle is greater than 130 nm [ 28 , 32 ].…”

“…Zinc oxide and its spatial derivatives such as nanowires and nanorods have proven to be a backbone material in a wide range of nanoscale electronic and photonic applications such as piezo-generators [1], field-effect transistors [2], light-emitting diodes [3], UV lasers [4], and waveguides [5]. Therefore it is really important to administer a controllable growth of ZnO nanowires and to monitor their optical properties.…”

“…The tasks performed by one nanomachine are very simple and restricted to its close environment due to its low complexity and small size. A nanomachines (Figure 1.3) consists of the following modules shown below: Nanotransceiver (nanoTRx) [11], Nanoprocessor [12], Nanomemory [13], Nanosensor [14] / Nanoactuator [15], and Nanobattery [16] / Nanoharvester [17]. Many breakthroughs in several branches of science (chemistry, physics, mechanics, electronics, telecommunications and computing) will be needed to make this vision reality in the long run.…”
