Nanopatterning of Weak Links in Superconducting Oxide Interfaces

Nanomaterials, 2021
The interface between two wide band-gap insulators, LaAlO3 and SrTiO3 (LAO/STO), hosts a quasi-two-dimensional electron gas (q2DEG), two-dimensional superconductivity, ferromagnetism, and giant Rashba spin-orbit coupling.

Deterministic integration of quantum dots into on-chip multi-mode interference beamsplitters using in-situ electron beam lithography

, 2017
The development of multi-node quantum optical circuits has attracted great attention in recent years. In particular, interfacing quantum-light sources, gates and detectors on a single chip is highly desirable for the realization of large networks.

Real-time generation of circular patterns in electron beam lithography

Nanotechnology and Precision Engineering
Electron beam lithography (EBL) involves the transfer of a pattern onto the surface of a substrate by first scanning a thin layer of organic film (called resist) on the surface by a tightly focused and precisely controlled electron beam (exposure) and ...

Electro‐Active Metasurfaces Controlling Exceptional Topological Phase Through Low‐Voltage Operation on Conductive Polymer

Advanced Functional Materials, EarlyView.
This research investigates an electro‐active chiral optical response (EACOR)‐driven dual‐channel metasurfaces with fast electrical switching rates of 52 ms, and a low operating voltage of 0.5 V. The combination of polyaniline (PANI) thin film and the exceptional topological (ET) phase of chiral gold (Au) meta‐atoms modulate holographic images through ...

Ternary Transistors With Reconfigurable Polarities

Advanced Functional Materials, EarlyView.
Polarity‐reconfigurable ternary transistors are demonstrated using black phosphorus homojunction with asymmetric contacts and split‐gate structures. Suppression of majority carrier injection, while Fowler–Nordheim tunneling of low‐density minority carriers persists, enables a well‐defined intermediate state with improved on/off ratios.

Changes in the near edge X-ray absorption fine structure of hybrid organic-inorganic resists upon exposure

, 2018
We report on the near edge X-ray absorption fine structure (NEXAFS) spectroscopy of hybrid organic-inorganic resists. These materials are nonchemically amplified systems based on Si, Zr, and Ti oxides, synthesized from organically modified precursors and
