A nanostructured cross-wire memory architecture is provided that can interface with conventional semiconductor technologies and be electrically accessed and read. The architecture links lower and upper sets of generally parallel nanowires oriented crosswise, with a memory element that has a characteristic conductance. Each nanowire end is attached to an electrode. Conductance of the linkages in the gap between the wires encodes the information. The nanowires may be highly-conductive, self-assembled, nucleic acid-based nanowires enhanced with dopants including metal ions, carbon, metal nanoparticles and intercalators. Conductance of the memory elements can be controlled by sequence, length, conformation, doping, and number of pathways between nanowires. A diode can also be connected in series with each of the memory elements. Linkers may also be redox or electroactive switching molecules or nanoparticles where the charge state changes the resistance of the memory element.

A photodetector cell may include a substrate, and a first contact carried by the substrate and having a first work function value. The photodetector cell may include a second contact carried by the substrate and having a second work function value different from the first work function value, and a semiconductor wire carried by the substrate and having a third work function value between the first and second work function values. The semiconductor wire may be coupled between the first and second contacts and comprising a photodiode junction.

Strain modulated nanostructures for optoelectronic devices and associated systems and methods are disclosed. A semiconductor laser in accordance with one embodiment of the disclosure, for example, comprises an active region having a nanowire structure formed from a semiconductor material. The nanowire structure of the semiconductor material has a bandgap that is indirect in a first strain state. The laser further includes a straining unit coupled to the active region. The straining unit is configured to modulate the nanowire structure such that the nanowire structure reaches a second strain state in which the bandgap becomes direct or substantially direct and, in operation, emits photons upon electron-hole recombination.
