Abstract:
An imprint apparatus (100, 100', 200, 220) and method 300 employ an effective pressure P eff in imprint lithography. The imprint apparatus (100, 100', 200, 220) includes a compressible chamber (111) that encloses an imprint mold (120, 228a) having a mold pattern (122) and a sample (130, 228b) to be imprinted (300). The chamber (111) is compressed (330, 340, 350) to imprint (360) the mold pattern (122) on the sample (130, 228b). The mold (120, 228a) is pressed (350) against the sample (130, 228b) with the effective pressure P eff . The effective pressure P eff is controlled by a selected ratio A cavity /A contact of a cavity area A cavity of the chamber (111) to a contact area A contact between the mold (120, 228a) and the sample (130, 228b).

Abstract:
A decoding structure employs a main terminal (130), a first memristive switch (112) connected between the main terminal (130) and a first addressable terminal (132), and a second memristive switch (114) connected between the main terminal (130) and a second addressable terminal (134). The second memristive switch (114) is oriented so that a voltage polarity on the main terminal (130) that tends to turn the first memristive switch (112) on tends to turn the second memristive switch (114) off.
Abstract:
A memristive device (400) includes: a first electrode (405); a second electrode (425); a memristive matrix (415) interposed between the first electrode (405) and the second electrode (425); a porous dopant diffusion element (410) in physical contact with the memristive matrix (415) and in proximity to the first electrode (405) and the second electrode (425); and a first mobile dopant species which moves through the porous dopant diffusion element (410) in response to a programming electrical field. A method for using a memristive device (400) having a porous dopant diffusion element (410) includes applying a voltage bias to generate a programming electrical field such that dopants move through the porous dopant diffusion element (410), thereby changing the distribution of dopants within a memristive matrix (415) to form a first state; removing the voltage bias, the dopants being substantially immobile in the absence of the programming electrical field; and applying a reading energy to the memristive device (400) to sense the first state.

An electrically actuated device includes a first electrode, a second electrode, and an active region disposed between the first and second electrodes. The device further includes at least one of dopant initiators or dopants localized at an interface between i) the first electrode and the active region, or ii) the second electrode and the active region, or iii) the active region and each of the first and second electrodes.
Abstract:
A multilayer memristive device includes a first electrode (410); a second electrode (405); a first memristive region (430) and a second memristive region (435) which created by directional ion implantation of dopant ions (420, 425) and are interposed between the first electrode (410) and the second electrode (405); and mobile dopants (315) which move within the first memristive region (430) and the second memristive region (435) in response to an applied electrical field.
Abstract:
A method for forming quantum dots (11 ) includes forming a superlattice structure (18) that includes at least one nanostrip (40, 42) protruding from the superlattice structure, providing a quantum dot substrate (14), transferring the at least one nanostrip to the quantum dot substrate, and removing at least a portion of the at least one nanostrip from the substrate. The superlattice structure is formed by providing a superlattice substrate (32), forming alternating layers of first and second materials (20, 24) on the substrate to form a stack, cleaving the stack to expose the alternating layers, and etching the exposed alternating layers with an etchant that etches the second material at a greater rate than the first to form the at least one nanostrip.
