Abstract
Embodiments of the present invention are directed to methods for fabricating microscale-to-nanoscale interfaces. In numerous embodiments of the present invention, hybrid microscale/nanoscale crossbar multiplexers/demultiplexers provide for selection and control of individual nanowires through a set of microscale signal lines. In order to overcome the difficulty of aligning nanowires with submicroscale and microscale signal lines, at least a portion of the interconnections between nanowires and sub-microscale or microscale signal lines are randomly generated by one of various connection-fabrication methods. Addresses for individual nanowires, or groups of nanowires, can be discovered by testing the microscale-to-nanoscale interfaces.
Claims29
A random microscale-to-nanoscale interface comprising:
- a number N of approximately parallel nanowires;
- a number M, where M>log2N, of approximately parallel microscale or sub-microscale address signal lines that are not parallel with respect to the N nanowires and that form a grid-like set of intersections with the N nanowires;
- and
- a random or pseudorandom distribution of interconnections within the grid-like set of intersections.
A method for fabricating a nanoscale or microscale/nanoscale crossbar, the method comprising:
- fabricating a number N of approximately parallel nanowires;
- fabricating a number M, where M>log2N, of approximately parallel microscale or sub-microscale address signal lines that are not parallel with respect to the N nanowires and that form a grid-like set of intersections with the N nanowires;
- and
- randomly or pseudo-randomly fabricating interconnections within the grid-like set of intersections.
