Nano-electron fluidic logic (NFL) device

A nano-electron fluidic logic (NFL) device that controls propagation of at least one bias surface plasma wave (bias SPW) in the absence of at least one control SPW in a wave guiding structure, the device comprising:

• a metallic gate patterned in accordance with a plurality of geometrical parameters;
• a plurality of source terminals, the source terminals include SBias, SC1, SC2, at which the plurality of SPWs is launched;
• and
• a plurality of drain terminals, the drain terminals include DO1, DO2, at which the plurality of SPWs is detected;
• whereby the bias SPW splits substantially into equal portions that may be detected at at least one drain terminal (DO1, DO2), and
• whereby the device controls propagation of the at least one bias SPW by Plasmon-plasmon scattering.

A method for controlling the launching and propagation of at least one surface plasma wave (SPW) in a nano-electron fluidic logic (NFL) operation, the method comprising the steps of:

• creating a patterned two-dimensional electron gas (2DEG) underneath at least one patterned metallic gate, the 2DEG being biased so as to behave as an electron fluid (EF);
• launching the at least one bias SPW on the 2DEG fluid;
• launching a control SPW at an angle to the bias SPW on the 2DEG fluid;
• propagating on the 2DEG fluid by plasmon-plasmon scattering, specifically, by interacting and colliding the bias SPW and the control SPW;
• and
• detecting at least one output SPW with at least one momentum vector ({right arrow over (k)}01, {right arrow over (k)}02) in the direction of at least one drain terminal (DO1, DO2).
