Recent developments in semiconductor industry: Two case studies

Abstract

[EN] Recent studies predict a four times larger global economy that today employ 80% more energy in 2050. Currently about 2% of the electricity produced in a conventional power plant is harvested, the rest is lost as heat in the central and transport processes. It is in this context that recovers important renewable energy and increasing efficiency. Semiconductor Materials may be an alternative to such industrial challenges. Recent advances for nanodevices present Silicon Germanium as thermoelectric materials heat recovery nanostructures at high temperatures and Aluminum Nitride as a substrate for piezoelectric devices used as Sensors Acoustic Wave (SAW). Piezoelectric injectors may help to control it more precisely the injection times and the amount of fuel that is inserted into the combustion engine helping to reduce fuel consumption on the other hand vehicles. For recover the energy lost as heat making electricity with a thermoelectric generator could save up to 10% in fuel consumption.
