NANOFABRICATION AND SCANNING PROBE LITHOGRAPHY Introduction: “Nanofabrication” is the process of making functional structures with arbitrary patterns having minimum dimensions currently defined (more-or-less arbitrarily) to be e100 nm. Microelectronic devices and information technologies have improved and will continue to improve as a result of large-scale‚ commercial implementation of nanofabrication. The motivation for these improvements is to increase the density of components

CHAPTER I INTRODUCTION Mortar Adhesive is a very expensive construction material commonly used in building houses‚ parts of the house and other infrastructures like buildings‚ etc. Mortar is a very expensive ingredient that bonds bricks‚ stones‚ tiles‚ and concrete blocks into a structure. On the other hand Mollusk Shells specifically Mussel Shells and Oyster Shells are commonly consumed as food or used in pearl production. But once the meat of the shell is eaten or the pearl is removed‚ these

The Split-type air conditioner Some rooms do not have external windows or walls. Difficulties arouse in creating sufficient air flow in the rooms‚ which can lead to discomfort for residents in terms of temperature and humidity. The split-type air conditioner can be used in these situations. Introduction: A split air conditioning simply means that the condensor (or sometimes referred to as the “outdoor unit”) is separated from the “indoor unit”‚ thus the term “split”. The split air conditioning

thermistors to modern data acquisition systems. Thermistor Overview A thermistor is a piece of semiconductor made from metal oxides‚ pressed into a small bead‚ disk‚ wafer‚ or other shape‚ sintered at high temperatures‚ and finally coated with epoxy or glass. The resulting device exhibits an electrical resistance that varies with temperature. There are two types of thermistors – negative temperature coefficient (NTC) thermistors‚ whose resistance decreases with increasing temperature‚ and positive

Power MOSFET From Wikipedia‚ the free encyclopedia Jump to: navigation‚ search Two power MOSFETs in the surface-mount package D2PAK. Each of these components can sustain a blocking voltage of 120 volts and a continuous current of 30 amperes. A power MOSFET is a specific type of metal oxide semiconductor field-effect transistor (MOSFET) designed to handle significant power levels. Compared to the other power semiconductor devices‚ for example IGBT‚ Thyristor‚ its main advantages are high
