Terahertz (unit)
The hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI), often described as being equivalent to one event (or cycle) per second. The hertz is an SI derived unit whose formal expression in terms of SI base units is 1/s or s−1, meaning that one hertz is one per second or the reciprocal of one second. It is used only in the case of periodic events. It is named after Heinrich Rudolf Hertz (1857–1894), the first person to provide conclusive proof of the existence of electromagnetic waves. For high frequencies, the unit is commonly expressed in multiples: kilohertz (kHz), megahertz (MHz), gigahertz (GHz), terahertz (THz). Some of the unit's most common uses are in the description of periodic waveforms and musical tones, particularly those used in radio- and audio-related applications. It is also used to describe the clock speeds at which computers and other electronics are driven. The units are sometimes also used as a representation of ...

Terahertz Radiation
Terahertz radiation – also known as submillimeter radiation, terahertz waves, tremendously high frequency (THF), T-rays, T-waves, T-light, T-lux or THz – consists of electromagnetic waves within the International Telecommunication Union-designated band of Frequency, frequencies from 0.1 to 10 Hertz#SI prefixed forms of hertz, terahertz (THz), (from 0.3 to 3 Hertz#SI prefixed forms of hertz, terahertz (THz) in older texts, which is now called "decimillimetric waves" ), although the upper boundary is somewhat arbitrary and has been considered by some sources to be 30 THz. One terahertz is 1012 Hertz, Hz or 1,000 GHz. Wavelengths of radiation in the decimillimeter band correspondingly range 1 mm to 0.1 mm = 100 μm and those in the terahertz band 3 mm = 3000 μm to 30 μm. Because terahertz radiation begins at a wavelength of around 1 millimeter and proceeds into shorter wavelengths, it is sometimes kno ...

Terahertz Spectroscopy And Technology
Terahertz spectroscopy detects and controls properties of matter with electromagnetic fields that are in the frequency range between a few hundred gigahertz and several terahertz (abbreviated as THz). In many-body systems, several of the relevant states have an energy difference that matches with the energy of a THz photon. Therefore, THz spectroscopy provides a particularly powerful method in resolving and controlling individual transitions between different many-body states. By doing this, one gains new insights about many-body quantum kinetics and how that can be utilized in developing new technologies that are optimized up to the elementary quantum level. Different electronic excitations within semiconductors are already widely used in lasers, electronic components and computers. At the same time, they constitute an interesting many-body system whose quantum properties can be modified, e.g., via a nanostructure design. Consequently, THz spectroscopy on semiconductors is releva ...

Intel TeraHertz
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. One element of this structure is a "depleted substrate transistor," which is a type of CMOS device where the transistor is built in an ultra-thin layer of silicon on top of an embedded layer of insulation. This ultra-thin silicon layer is fully depleted to maximize drive current when the transistor is turned on, allowing the transistor to switch on and off faster. In contrast, when the transistor is turned off, unwanted current leakage is minimized by the thin insulating layer. This allows the depleted substrate transistor to have 100 times less leakage than traditional silicon-on-insulator schemes. Another innovation of Intel's de ...
