Using negative capacitance in the isolaton layer MOSFET gates 30 % less voltage is needed for switching the MOSFETs <quote>The researchers found that a superlattice structure composed of three atomic layers of zirconium oxide sandwiched between two single atomic layers of hafnium oxide, totaling less than two nanometers in thickness, provided the best negative capacitance effect. <end quote>
