Claim:
1. A phonon transistor comprising: electrical contacts; two quantum dots embedded in a semiconductor such that when an electrical bias is applied to the electrical contacts, an electric field produced by the electrical bias is substantially parallel to an axis through the two quantum dots, wherein the two quantum dots include a first and second quantum dot, wherein the first quantum dot and the semiconductor provide a continuum state, wherein the second quantum dot provides a discrete state, wherein the continuum state and the discrete state are coupled when the electrical bias is applied to the electrical contacts, and wherein the electrical bias provides a gating mechanism for the coupling such that when the electrical bias includes a first electro potential the electric field inhibits the generation or transmission of phonons and when the electrical bias includes a second electro potential different from the first electro potential, the electrical field promotes the generation or transmission of phonons; and a phononic wave guide coupled to the semiconductor, the phononic wave guide configured to transport phonons therethrough.
