Intel TeraHertz was Intel's new design for transistors. It uses new materials such as zirconium dioxide which is a superior insulator reducing current leakages. Using zirconium dioxide instead of silicon dioxide, this transistor can reduce the current leakage, and thus reduces power consumption while still working at higher speed and using lower voltages.

In physics, terahertz radiation – also known as submillimeter radiation, terahertz waves, tremendously high frequency, T-rays, T-waves, T-light, T-lux or THz – consists of electromagnetic waves within the ITU-designated band of frequencies from 0.3 to 3 terahertz (THz; 10¹² Hz). Wavelengths of radiation in the terahertz band correspondingly range from 1 mm to 0.1 mm (or 100 µm). Because terahertz radiation begins at a wavelength of one millimeter and proceeds into shorter wavelengths, it is sometimes known as the submillimeter band, and its radiation as submillimeter waves, especially in astronomy.
