“…[ 48,49 ] In a similar manner, the local strain applied to the Pd electrodes was also estimated to be ∼0.22% which is also small enough to keep the stable electrical performances under the pre-strain and releasing deformation. [ 50 ] By a serial connection of three SWCNT CMOS inverters, a ring oscillator can be fabricated and a stable device performance is expected only with the reproducible performance of the individual inverter. Optical microscope images of ring-oscillator array on SiO 2 substrate prior to the transfer onto PDMS, and those on PDMS substrate under different pre-strains are shown in Figure 7 (a).…”

The fabrication of a stretchable single-walled carbon nanotube (SWCNT) complementary metal oxide semiconductor (CMOS) inverter array and ring oscillators is reported. The SWCNT CMOS inverter exhibits static voltage transfer characteristics with a maximum gain of 8.9 at a supply voltage of 5 V. The fabricated devices show stable electrical performance under the maximum strain of 30% via forming wavy configurations. In addition, the 3-stage ring oscillator demonstrates a stable oscillator frequency of ∼3.5 kHz at a supply voltage of 10 V and the oscillating waveforms are maintained without any distortion under cycles of pre-strain and release. The strains applied to the device upon deformation are also analyzed by using the classical lamination theory, estimating the local strain of less than 0.6% in the SWCNT channel and Pd electrode regions which is small enough to keep the device performance stable under the pre-strain up to 30%. This work demonstrates the potential application of stretchable SWCNT logic circuit devices in future wearable electronics.

“…Equations (1), (4) and (5) constitute a two-parameter (  and  ) representation of the surface oxide-induced strain in the Pd wire. Young's Modulus for bulk Pd is 170 GPa [15] and that of PdO is estimated to be 169 GPa [16]. This leads to the…”

“…Mechanical propa e-mail: mgksp@uohyd.ernet.in erties assume importance especially in the case of thick films since surface layers of these films may be exposed to external mechanical effects including wear, damage and thermal degradation [21]. Recently, nanoindentation techniques have been employed extensively to quantify the mechanical properties of thin films [22][23][24][25] such as hardness, elastic modulus and adhesion. Among these, the adhesion of coatings to the substrates is a key factor for the mechanical behavior of coated parts [24].…”

Abstract. Structural, optical and nanomechanical properties of nanocrystalline Zinc Telluride (ZnTe) films of thickness upto 10 microns deposited at room temperature on borosilicate glass substrates are reported. X-ray diffraction patterns reveal that the films were preferentially oriented along the (1 1 1) direction. The maximum refractive index of the films was 2.74 at a wavelength of 2000 nm. The optical band gap showed strong thickness dependence. The average film hardness and Young's modulus obtained from loaddisplacement curves and analyzed by Oliver-Pharr method were 4 and 70 GPa respectively. Hardness of (1 1 1) oriented ZnTe thin films exhibited almost 5 times higher value than bulk. The studies show clearly that the hardness increases with decreasing indentation size, for indents between 30 and 300 nm in depth indicating the existence of indentation size effect. The coefficient of friction for these films as obtained from the nanoscratch test was ∼0.4.
