“…The relative height of the peak at 44.6 • is much larger than for the film with lower x indicating that some rock-salt phase might already be present. Nevertheless, the dominance of the spinel peak is a remarkable result since this is clearly beyond the stoichiometric composition x = 0.33 which has been reported to be the solubility limit for bulk material prepared by high-pressure sintering 35 and for samples fabricated by solution-based methods. 20 The possibility of obtaining (Ni x Co 1−x ) 3 O 4 with a high Ni content x was however also reported by Windisch et al 20 for sputtered films.…”

We report the atomic layer deposition (ALD) of high-quality crystalline thin films of the spinel-oxide system (Co 1−x Ni x ) 3 O 4 . These spinel oxides are ferrimagnetic p-type semiconductors promising for several applications ranging from photovoltaics and spintronics to thermoelectrics. The spinel phase is obtained for Ni contents exceeding thex = 0.33 limit for bulk samples. It is observed that the electrical resistivity decreases continuously with x while the magnetic moment increases up to x = 0.5. This is in contrast to bulk samples where a decrease of resistivity is not observed for x > 0.33 due to the formation of a rock-salt phase. From UV-VIS-NIR absorption measurements, a change from distinct absorption edges for the parent oxide Co 3 O 4 to a continuous absorption band ranging deep into the near infrared for 0 < x ≤ 0.5 was observed. The conformal deposition of dense films on high-aspect-ratio patterns is demonstrated.

The internet plays a pivotal role in Industry 4.0, where it provides the underlying infrastructure to support the substantial growth of digital platforms and systems to deliver a wealth of benefits. However, with the unprecedented growth of internet-based applications in recent history, the internet itself is harming the environment. Focusing on individual green motivation and willingness to pay for the green internet, this study explores one’s willingness to reduce internet usage. The study employs a survey experiment that involves 376 respondents. The results show that the most effective strategy to reduce internet usage is to incorporate extrinsic strategies and allow individuals to pay a premium for green internet services. Our work contributes to the Industry 4.0 literature by exploring how the negative environmental effects of consumerization of IT can be minimized. The findings of the study are important for technology-based businesses, policy-makers and individuals seeking to reduce the environmental damage of the internet.
