Vanadium Dioxide | MSE 510 Term Paper | Shamus E. O'Keefe Dec. 5, 2012 | Vanadium oxides are interesting materials owing to their unique physical and chemical properties. Vanadium dioxide (VO2) may be the most interesting, and as a result possibly the most studied of the class. VO2 is a strongly correlated electron system that exhibits a dramatic metal-insulator transition (MIT) near room temperature. In addition to the MIT, VO2 has also been shown to possess high

Chapter 3 Introduction to Microcontrollers 3.1 Just a Start Up A microcontroller (also MCU or ¥ìC) is a computer-on-a-chip. It is a type of micro-computer element that emphasizing high integration, low power consumption, self-sufficiency and cost-effectiveness, in contrast to a general-purpose microprocessor. In addition to the usual arithmetic and logic elements of a general purpose microprocessor, the microcontroller typically integrates additional elements such as read-write memory for

Application Note Turning Varactors Introduction Tuning varactors are voltage variable capacitors designed to provide electronic tuning of oscillators and filters. The two semiconductor materials used are silicon and gallium arsenide. Silicon typically offers lower manufacturing cost, while gallium arsenide diodes provide higher Q and may be used at higher microwave frequencies. Within the general family of tuning varactors, there are several major categories, each designed for particular
