The reliability of vanadyl-phthalocyanine (VOPc) thin film transistors (TFTs) with silicon nitride (SiNx) gate insulator was investigated under bias stress conditions. The shift of threshold voltage in ambient air, in vacuum and at high temperature was discussed. The initial field-effect mobility and threshold voltage were 1.2cm2/Vs and −4.22V, respectively. After a gate bias stress of −20V for 10,000s...
Inertial sensing is of paramount importance for a wide variety of navigation, guidance and control tasks. Historically, application of inertial sensing was limited to high-performance, high-cost aerospace and military fields. Recent MEMS technology has enabled miniaturization, mass production, and cost reduction of inertial sensors. This paper presents the development and robotic application of a...
This paper analyzed some advantages and disadvantages of wireless sensor network protocols, and concluded the features of it. According to the features, the program members summarized its influence on the routing protocols, designed the models based on it and improved algorithms. They simulated the findings with OMNeT++, showing the rotation of cluster head can efficiently increase the lifetime of...
