Carlos Paz de Araújo

Résumé
Carlos A. Paz de Araújo (born in Natal) is a Brazilian American scientist and inventor with nearly 600 patents registered in his name. Most of them are associated with nanotechnology, particularly a ferroelectric memory chip (FeRAM) Career and inventions As a professor of electrical and computer engineering at the University of Colorado at Colorado Springs, Paz de Araujo's work has led to the development of integrated circuit-embedded FeRAMs used in smart cards, electronic money and other products. Paz de Araújo is the founder of RAMTRON and Symetrix Corporations. He identified SrBi2Ta203 (SBT), the ferroelectric material used in the most advanced FeRAMs and which resolves the fatigue problem and fabrication difficulties in memory chips, ensuring that stored information is retained. Paz de Araujo and his colleagues were the first to use ferroelectric thin films as high-k capacitors for cellular phones, integrated on a set of gallium arsenide chips. The resulting devices w
