Flux-Assisted Growth of Degenerate n-Type SnSe2 Layers

Seoungbum Lim, Xingguo Wang, Chan How Oh, Yuhui Yang, Yue Gong, Chenyu Zang, Manlin Luo, Xingli Wang, Philippe Coquet, Edwin Teo, Sang Hoon Chae, Beng Kang Tay

Tin diselenide (SnSe2) is a two-dimensional (2D) semiconductor with a high electron affinity (∼5.2 eV) and inherent n+-type conductivity. While conventional chemical vapor deposition (CVD) has been investigated for the growth of SnSe2, the domain sizes are typically limited to ∼50 μm. This…

A hybrid Volume of Fluid Phase-Field method for Direct Numerical Simulations of soluble surfactant-laden interfacial flows

Ilies Haouche, Benjamin Reichert, Michaël Baudoin, Palas Kumar Farsoiya

We present a hybrid Volume-of-Fluid (VoF) and Phase-Field method for general soluble surfactant-laden interfacial flows. The scheme retains the VoF method for interface tracking and momentum solution, while a diffused Phase-Field serves as a smooth carrier for surfactant transport enabling…

Microfabricated vapor cells with tunable buffer gas mixtures using laser-actuated break-seal reservoirs

Clément Carlé, Gabriel Faure, Andrei Mursa, Shervin Keshavarzi, Quentin Tanguy, Emmanuel Klinger, Vincent Maurice, Rodolphe Boudot, Nicolas Passilly

Microfabricated cells are the core component of a wide variety of chip-scale atomic devices, such as clocks or magnetometers [1]. In those instruments, the cell is generally filled with a pressure of buffer gas. The presence of buffer gas reduces the atom-wall collision rate, enhances the atomic…

Waveguide-pair design co-optimization and tolerance study for hybrid III-V/Si quantum dot DBR lasers

Konstantinos Papatryfonos, Peter Raymond Smith, David Selviah

<div><p>The development of compact, energy-efficient integrated lasers operating at 1.3 µm remains a central goal in silicon photonics, driven by the needs of data communication and optical interconnect applications. In this study, we investigate the lateral co-optimization of the…

Low-defect quantum dot lasers directly grown on silicon analyzed using cross-sectional scanning tunneling microscopy and spectroscopy

Konstantinos Papatryfonos, Jean-Christophe Girard, Mingchu Tang, Christophe David, Alwyn Seeds, Guillemin Rodary, Huiyun Liu, David Selviah

<div><p>Monolithic integration of III-V lasers on silicon is a central objective of silicon photonics, yet direct heteroepitaxy remains challenged by lattice and thermal-expansion mismatches that generate dislocations and other extended defects. Here we report an optimized molecular…

Fundamental thermovisco mechanical interactions governing the acoustic response of laser-excited nanoparticles

Stefano Giordano, Michele Diego, Francesco Banfi, Michele Brun

In this work, we investigate the thermoacoustic generation and propagation of spherical waves in a viscous fluid induced by a laser-heated spherical particle. Periodic laser excitation gives rise to two coupled mechanisms of acoustic emission. Heat transfer from the particle to the surrounding…

Coexistence and interplay of Fabry–Pérot and twin Friedrich–Wintgen bound states in the continuum in a plasmonic double T-cavity

Amina Rezzouk, Soufyane Khattou, Madiha Amrani, Adnane Noual, El Houssaine El Boudouti, Bahram Djafari-Rouhani

Bound states in the continuum (BICs) are typically investigated in terms of distinct formation mechanisms, such as symmetry-protected (SP), Friedrich–Wintgen (FW), or Fabry–Pérot (FP) BICs. However, their coexistence and mutual interaction within a single plasmonic architecture have not been…
