Enhancement of optical response in nanowires by negative-tone PMMA lithography

, 2018
The method of negative-tone-PMMA electron-beam lithography is investigated to improve the performance of nanowire-based superconducting detectors. Using this approach, the superconducting nanowire single-photon detectors (SNSPDs) have been fabricated ...

SCALPEL: projection electron beam lithography [PDF]

Proceedings of the 1999 Particle Accelerator Conference (Cat. No.99CH36366), 2003
Even though virtually all integrated circuits over the past 30 years have been made using optical lithography, the limits of its usefulness are on the horizon. From the point of view of the physics of the image formation process, it is difficult to imagine practical processes operating at feature sizes at or near half the wavelength of the exposure ...

Color Routing and Beam Steering of Single‐Molecule Emission with a Spherical Silicon Nanoantenna

Advanced Functional Materials, EarlyView.
We experimentally demonstrate broadband directional emission from single molecules using a single spherical silicon nanoparticle assembled via DNA origami. By varying nanoparticle (NP) size and emitter position, we achieve unidirectional emission, beam steering, and color routing at the nanoscale, revealing modal interference as the underlying ...

Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

Advanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

Overlapping-gate architecture for silicon Hall bar MOSFET devices in the low electron density regime

, 2010
We report the fabrication and study of Hall bar MOSFET devices in which an overlapping-gate architecture allows four-terminal measurements of low-density 2D electron systems, while maintaining a high density at the ohmic contacts. Comparison with devices

Bio‐Inspired Multimodal Hardware Front‐End Enabled by 2D Floating‐Gate Memory for UAV Perception

Advanced Functional Materials, EarlyView.
A MoS2/h‐BN /graphene floating‐gate memory underpins a bio‐inspired multimodal front end that integrates visual, inertial, and airflow cues. A 4 × 4 FG memory array encodes temporal intensity differences, while IMU‐ and airflow‐driven threshold modulation suppresses self‐motion artifacts, enabling fast, low‐power, robust autonomous UAV tracking and ...

Transmitted electron exposure in electron beam lithography for double-side patterning of bi-layer metasurfaces on a SiNx membrane

Micro and Nano Engineering
Metasheets, composed of two identical metasurfaces closely aligned to each other within a mode-coupling distance on the two opposite sides of a SiNx membrane, are of unique functionalities for effective modulation of electromagnetic waves by nanoscale ...

Fabrication of high quality sub-micron Au gratings over large areas with pulsed laser interference lithography for SPR sensors

, 2012
Metallic gratings were fabricated using high energy laser interference lithography with a frequency tripled Nd:YAG nanosecond laser. The grating structures were first recorded in a photosensitive layer and afterwards transferred to an Au film.
