Monolithic Oxidation Enables Ultrathin Vertically Graded Tantalum Oxide for Low‐Voltage, Low‐Variability Memristive Switching

Advanced Functional Materials, EarlyView.
Monolithic UV‐ozone oxidation of Ta forms an ultrathin Ta2O5/TaOx bilayer enabling resistive switching with a vertical defect gradient. A stoichiometric surface layer over an oxygen‐deficient sublayer promotes localized filament nucleation near the top interface, enabling low‐voltage operation, and reduced cycle‐to‐cycle variability.

A Reconfigurable Optical Logic Gate With up to 25 Logic Functions Based on Polarization Modulation With Direct Detection

IEEE Photonics Journal, 2017
We propose and investigate a new scheme to realize optical logic gates using polarization addition with direct detection. Two polarizations of an optical signal are modulated, respectively, by independent binary inputs to represent four different states,

Sensitivity of a Chaotic Logic Gate

IEEE Transactions on Circuits and Systems II: Express Briefs, 2022
Chaotic logic gates or `chaogates' are a promising mixed-signal approach to designing universal computers. However, chaotic systems are exponentially sensitive to small perturbations, and the effects of noise can cause chaotic computers to fail. Here, we examine the sensitivity of a simulated chaogate to noise and other parameter variations (such as ...

Semiconducting Polymers Post‐Functionalized With Ureido‐Pyrimidinone for Robust Stretchable Transistors

Advanced Functional Materials, EarlyView.
The design of intrinsically robust stretchable semiconducting polymers was achieved through OTBS‐mediated post‐functionalization of PDPP2T side chains with UPy units, generating dual hydrogen‐bonding motifs comprising weaker urethane linkages and strong quadruple UPy interactions along the long alkyl side chain, which is crucial for achieving desirable

Tunable Complementary Doping Strategy Enables High‐Performance Homo‐Channel CMOS in Monolayer WSe2

Advanced Functional Materials, EarlyView.
Polarity‐selective modulation enables a homo‐channel WSe2 CMOS platform from a single 2D semiconductor. MoOx and AlN tune WSe2 toward p‐ and n‐type operation, respectively, yielding complementary FETs and inverters with balanced switching, high voltage gain, low static power, and promising scalability for 2D logic integration.
