Transport properties of pristine and alloyed free standing ultrathin nanowires of noble metals

Si and Ge based metallic core/shell nanowires for nano-electronic device applications

“…This is an essential property for fast switching in the atomic scale devices. The NDC effect is observed in multiple voltage regions for the As/Ge (R) NW, in the windows 0.5–0.7 V and 0.8–1.0 V. The NDC effect in multiple region of I-V curve has also been observed in AgPt alloyed nanowire in a previous study 58 . The effect is seen in the region 0.3–0.5 V for the As/Si (R) NW as shown in Fig.…”

H2S and NH3 adsorption characteristics on CoO nanowire molecular device – A first-principles study

“…Even though, some of the reports are available based on cobalt oxide as a gas sensor, still the selectivity and sensitivity should be enhanced on the base material. Moreover, the working principle of CoO nanowire sensors can be studied with the help of device modelling methods like density functional theory (DFT) combined with non-equilibrium Green's function (NEGF) [20]. The aim of the present work is to study the gas sensing properties of CoO nanowires upon H 2 S and NH 3 gases, which are discussed in terms of electronic transport properties.…”

Effects of rapid thermal annealing for E-beam evaporated Ag films on stainless steel substrates

“…In particular, noble metal films (e.g., gold (Au), platinum (Pt) and silver (Ag) [1][2][3][4]) have a wide range of applications in modern electronic and photonic systems, including catalysis [5], optics [6], and bio-sensing [7]. In addition, silver thin films have been extensively studied as they are easy to prepare and have novel optical properties [8,9].…”
