Recently, engineers at the University of California, Berkeley, described a breakthrough in the design of transistors (tiny electronic switches that make up computer building blocks) that can dramatically reduce their power consumption without sacrificing speed, size, or performance. This element is called the gate oxide layer, which plays a crucial role in switching transistors.
In this study, the team also achieved negative capacitance by combining hafnium and zirconium oxide in an engineered crystal structure called superlattice, which allowed both ferroelectricity and antiferroelectricity to exist simultaneously. These transistors were found to require about 30% less voltage than existing transistors while maintaining the semiconductor industry benchmark without sacrificing reliability.
This test of Zirconia's new application further shows that the development potential of zirconia ceramic components is enormous. The traditional application of zirconia is mainly to zirconia ceramic axes and structural ceramic components, as raw material for refractories, coatings, glazes, etc. With a deep understanding of the thermodynamic and electrical properties of zirconia ceramics, it is possible to widely use it as a high-performance solid dielectric and structural ceramic material.
