Multi‐Level Saturation Current Encoding in Two‐Dimensional Ferroelectric Source‐Gated Transistors

Advanced Functional Materials, EarlyView.
A 2D ferroelectric source‐gated transistor (SGT) operates with a non‐volatile, multi‐level saturation current controlled by ferroelectric polarization. Operando electrostatic and photocurrent imaging link the current limitation to source‐side depletion, identifying saturation current as a programmable, read‐bias‐tolerant device parameter toward low ...

Engineered Nanotopography to Modulate Growth and Signaling of Neuronal Networks

Advanced Functional Materials, EarlyView.
This study examines the interaction between neurons and nanoscale topographies on engineered substrates. Neurons cultured on nanowires, nanopillars and nanoneedles exhibit enhanced neurite outgrowth, form more organized neuronal circuits, and display improved synaptic connectivity, compared to flat substrates.

Integrated optics-devices

Physics in Technology, 1983
The main advantages of integrated optics devices lie in the inherent simplicity of all-optical systems and high switching speeds (>5 Gbit s-1). The outstanding device problems include the connection of optical fibres to these microcircuits and the integration of many devices on a single chip.

Optical Characterization Of Integrated Optical Devices

SPIE Proceedings, 1988
As integrated optical components become increasingly available, the need for an understanding of methods for characterization of these devices becomes necessary. This paper discusses several techniques for characterization of Ti:LiNb0 3 devices including waveguides, polarizers and phase modulators.
