Ozone-enhanced molecular beam deposition of nickel oxide (NiO) for sensor applications

Synthesis and characteristics of NiO nanowire by a solution method

“…NiO has also become very important for it can be used as electrode materials in battery systems [7,8]. Nonstoichiometric nickel oxide is a good P-type semiconductor owing to its defect structure [9,10] and it is also a potential gas sensor for NO 2 [11][12][13], NH 3 [14], and H 2 [15]. The recently observed electrochromic behavior makes its possible application in ''smart windows'' with variable light transmission characteristics [16,17].…”

Humanitarian Demining Using an Insect Based Chemical Unmanned Aerial Vehicle

“…In addition, the limit of the sensitivity of the thin metal oxide chemo-sensing technology, and in particular the applicability to the particular case of the detection of leaking explosives has to be further assessed. It has been shown that the sensitivity of this type of technology can go up to few parts per million (ppm), providing a wide range sensitivity that allows for identification of organic compounds (Neubecker et al 1997;Eickhoff et al 2003). Nevertheless, the chemical traces of some explosives such as TNT are shown to be made of few parts per billion (ppb) (Rose et al 2005).…”

Various Structures Based on Nickel Oxide Thick Films as Gamma Radiation Sensors

“…Electrochromic materials, for example Nickel oxide, are used in applications such as energy efficient "smart windows", glare-free and variable reflectance mirrors, high-contrast non-emissive information displays, switchable displays, devices for thermal control, semiconductor-based sensors, etc. [5,6]. In this work a number of NiO based thick films of various structures were investigated in terms of their use as gamma radiation sensors.…”
