Influence of target-substrate distance during pulsed laser deposition on properties of LiNbO3 thin films

This paper shows the results of studying the influence of target-substrate distance during pulsed laser deposition on electrical properties of LiNbO3 thin films. It has been shown that changing the target-substrate distance we can obtain thin films with a different composition. EDX spectra indicate that the LiNbO3 thin films fabricated under 120 mm target-substrate distance depleted Nb (0.7 atm. %) compare to LiNbO3 films fabricated under 20 mm target-substrate distance (11.0 atm. %). Varying target-substrate distance in the range from 20 mm to 120 mm charge carrier mobility increasing from 24 cm2/Vcenterdots to 395 cm2/Vcenterdots and concentration of charge carrier decreasing from 3centerdot1013 cm-3 to 1centerdot1012 cm-3. Obtained results can be used under development and fabrication of integral acousto-optic and surface acoustic wave (SAW) devices

Technology Roadmap for Flexible Sensors

Humans rely increasingly on sensors to address grand challenges and to improve quality of life in the era of digitalization and big data. For ubiquitous sensing, flexible sensors are developed to overcome the limitations of conventional rigid counterparts. Despite rapid advancement in bench-side research over the last decade, the market adoption of flexible sensors remains limited. To ease and to expedite their deployment, here, we identify bottlenecks hindering the maturation of flexible sensors and propose promising solutions. We first analyze challenges in achieving satisfactory sensing performance for real-world applications and then summarize issues in compatible sensor-biology interfaces, followed by brief discussions on powering and connecting sensor networks. Issues en route to commercialization and for sustainable growth of the sector are also analyzed, highlighting environmental concerns and emphasizing nontechnical issues such as business, regulatory, and ethical considerations. Additionally, we look at future intelligent flexible sensors. In proposing a comprehensive roadmap, we hope to steer research efforts towards common goals and to guide coordinated development strategies from disparate communities. Through such collaborative efforts, scientific breakthroughs can be made sooner and capitalized for the betterment of humanity
