Study on 𝛾-Rays Irradiation Induced Structural and Morphological Changes in Copper Nanowires | Chapter 7 | Recent Trends in Chemical and Material Sciences Vol. 4

 The influence of -irradiations on the structural and morphological features of copper nanowires (Cu-NWs) at doses ranging from 6 to 25 kGy is discussed in this paper. Cu-NWs began welding at 9 kGy, generating flawless X-, V-, II-, and Y-shaped molecular connections. The Cu-NWs fused and formed bigger diameter NWs as the dose was increased to 15 kGy. The nanowires changed into a continuous Cu thin film at the greatest dose of 25 kGy. The structure of the Cu-NWs remained constant following conversion into a thin film, according to X-ray diffraction (XRD) measurements. At larger doses, the Cuprite (Cu2O) phases were seen to develop. The short and high energy -ray wavelengths that act isotropically on Cu-Cu molecular covalent bonds explain how welded networks of Cu-NWs and Cu thin films arise. The welding process is used to create large-scale structures that resemble junctions. These nano gadgets are beneficial to the nanoelectronics and nanocircuit industries.
