Generally discussed herein are techniques for and systems and apparatuses configured to control phonons using an electric field. In one or more embodiments, an apparatus can include electrical contacts, two quantum dots embedded in a semiconductor such that when an electrical bias is applied to the electrical contacts, the electric field produced by the electrical bias is substantially parallel to an axis through the two quantum dots, and a phononic wave guide coupled to the semiconductor, the phononic wave guide configured to transport phonons therethrough...
The phonon control mechanism (e.g., phonon FET) can be used to control the flow of phonon heat so as to increase an efficiency in which heat is dissipated or increased or to more precisely direct a flow of heat. The phonon control mechanism can be used as an interface between photonic logic (light based, for example fiber optic), electronic logic (electron based logic), phononic logic (phonon based logic), or spintronics (spin based logic). The phonon control mechanism can be used in quantum information technologies (e.g., for revealing coherent coupling between quantum structures). The phonon control mechanism can be used as a logic element in an information system (e.g., a solid state based information system) or processing technology, such as by using the phonon control mechanism as a logic switch. The phonon control mechanism can reduce noise caused by a phonon and can be used in an application to exploit its noise reducing ability, such as in a sensor or detector technology (e.g., light or TeraHertz radiation detector). Yet another application of the phonon control mechanism is in the field of solar technology where a high light absorption and reduced thermal emmittance can be advantageous, such as can be provided by the phonon control mechanism. The phonon control mechanism can be used in a strain or motion sensor,
