Efficient chip-based optical parametric oscillators from 590 nm to 1150 nm

December 2, 2022
Jordan Stone, Xiyuan Lu, Gregory Moille, Kartik Srinivasan
Optical parametric oscillators are a ubiquitous technology used to generate coherent light at frequencies not accessible by conventional laser gain. However, chip-based parametric oscillators operating in the visible spectrum have suffered from pump-to

Heterojunction tunnel triodes based on two-dimensional metal selenide and three-dimensional silicon

October 27, 2022
Jinshui Miao, Chloe Leblanc, Jinjin Wang, Yue Gu, Xiwen Liu, Baokun Song, Huairuo Zhang, Sergiy Krylyuk, Weida Hu, Albert Davydov, Tyson Back, Nicholas Glavin, Deep Jariwala
Low power consumption in the static and dynamic modes of operation is a key requirement in the development of modern electronics. Tunnel field-effect transistors with direct band-to-band charge tunnelling and steep-subthreshold-slope transfer

High-Throughput Nanopore Fabrication and Classification Using Xe-Ion Irradiation and Automated Pore-Edge Analysis

September 26, 2022
Michal Macha, Sanjin Marion, Mukesh Tripathi, Martina Lihter, Alex Smolyanitsky, Andras Kis, Aleksandra Radenovic
Large-area nanopore drilling is a major bottleneck in state-of-the-art nanoporous 2D membrane fabrication protocols. In addition, high-quality structural and statistical descriptions of as-fabricated porous membranes are key to predicting the corresponding

Size and Number Concentration Measurements of Polystyrene Nanoparticle Suspensions using Several Different Techniques

September 8, 2022
Paul C. DeRose, Kurt D. Benkstein, Elzafir B. Elsheikh, Adolfas K. Gaigalas, Sean Lehman, Dean C. Ripple, Linhua Tian, Wyatt N. Vreeland, Adam York, Yu-Zhong Zhang, Lili Wang
The number concentrations of nominal 100 nm, 200 nm and 500 nm diameter, fluorescently-labeled polystyrene nanosphere suspensions were measured using seven different techniques. Diameter values were also measured where possible. The diameter values were

Relative effects of polymer composition and sample preparation on glass dynamics

August 17, 2022
Christopher Soles, Amanda L. Forster, Katherine Evans, Madhusudan (Madhu) Tyagi, Robert M. Elder, Timothy Sirk, Joseph Dennis, Kanae Ito, Osama Yamamuro, Hiroshi Akiba
Modern design of common adhesives, composites and polymeric parts makes use of polymer glasses that are stiff enough to maintain their shape under a high stress while still maintaining a ductile behavior after the yield point. Typically, material

Broadband Nanoscale Surface-Enhanced Raman Spectroscopy by Multiresonant Nanolaminate Plasmonic Nanocavities on Vertical Nanopillars

August 8, 2022
Meitong Nie, Yuming Zhao, Wonil Nam, Junyeob Song, Wenqi Zhu, Henri Lezec, Amit Agrawal, Wei Zhou
Surface-enhanced Raman spectroscopy (SERS) has become a sensitive detection technique for biochemical analysis. Despite significant research efforts, most SERS substrates consisting of single-resonant plasmonic nanostructures on the planar surface suffer

Metasurface on integrated photonic platform: from mode converters to machine learning

July 20, 2022
Zi Wang, Yahui Xiao, Kun Liao, Tiantian Li, Hao Song, Haoshuo Chen, S M Zia Uddin, Dun Mao, Feifan Wang, Zhiping Zhou, Bo Yuan, Wei Jiang, Nikolas Fontaine, Amit Agrawal, Alan Willner, Xiaoyong Yu, Tingyi Gu
Integrated photonic circuits are created as a small form factor and robust analogue for fiber-based optical systems, from wavelength-division multiplication transceivers to more recent mode-division multiplex-ing components. Silicon nanowire waveguides

Revising quantum optical phenomena in adatoms coupled to graphene nanoantennas

June 8, 2022
Garnett W. Bryant, Miriam Kosik, Marvin Muller, Karolina Slowik, Andres Ayuela, Carsten Rockstuhl, Marta Pelc
Graphene flakes acting as photonic nanoantennas sustain strong electromagnetic field localization and enhancement. To exploit the field enhancement, quantum emitters such as atoms or molecules should be positioned in such close proximity to the flake that

Improved Accuracy for Calibrated Mass Distribution Measurements of Bimetallic Nanoparticles

May 23, 2022
Kaleb Duelge, George Mulholland, Antonio Montoro Bustos, Michael Zachariah, Michael Zachariah, John Pettibone
Implementation of hybrid nanoparticles (HNPs), consisting of two different metal components, into applied systems has been hindered by an incomplete understanding of structural and chemical properties responsible for their enhanced, yet inconsistent

Influence of Dimensionality on the Charge Density Wave Phase of 2H-TaSe2

March 23, 2022
Sugata Chowdhury, Albert Rigosi, Heather Hill, David B. Newell, Angela R. Hight Walker, Francesca Tavazza, Andrew Briggs
Metallic transition metal dichalcogenides like tantalum diselenide (TaSe2) exhibit exciting behaviors at low temperatures including the emergence of charge density wave (CDW) states. In this work, density functional theory (DFT) is used to classify the

Strong coupling between a topological insulator and a III-V heterostructure at terahertz frequency

March 8, 2022
Garnett W. Bryant, D. Quang To, Zhengtianye Wang, Q. Dai Ho, Ruiqi Hu, Wilder Acuna, Yongchen Liu, Anderson Janotti, Joshua Zide, Stephanie Law, Matthew Doty
We probe theoretically the emergence of strong coupling in a system consisting of a topological insulator (TI) and a III-V heterostructure using a numerical approach based on the scattering matrix formalism. Speci cally, we investigate the interactions

Impacts of ingested MWCNT-Embedded nanocomposites in Japanese medaka (Oryzias latipes)
