Cryogenic Quantum Sensing of hBN-Encapsulated 2D Materials
Bynatalierbaggett April 23, 2025May 7, 2025

Emilio Codecidoattocube systems, GmbH, Haar, Germany _______________________________________ We present a summary of recent notable results from our customer base using cryogenic quantum sensing techniques to study hBN-encapsulated two-dimensional (2D) materials. We highlight our recently launched nitrogen-vacancy (NV) scanning magnetometer’s capability to image magnetic textures and potential to image correlated phases such as those observed in…

Hexagonal boron nitride research in the Henriksen Lab
Bynatalierbaggett April 18, 2025

Yiwei Le and Jeree MurrayWashington University, St. Louis, Missouri, USA _______________________________________ We often employ hexagonal boron nitride in crafting ‘van der Waals heterostructure’ devices for exploring physics of graphene or other 2D materials. Here we describe two new projects that start with or rely on the physics of hBN. First, in collaboration with the lab…

Creating deterministically placed single photon emitters in hexagonal boron nitride
Bynatalierbaggett March 12, 2025

Richarda NiemannVanderbilt University, Nashville, Tennessee, USA _______________________________________ With the rapidly increasing interest in quantum information technologies the miniaturization of on-chip devices using quantum photonic circuits has become a critical field of research. A central building block for these circuits are single photon emitters (SPEs) [1]. It was shown that a variety of materials can host…

Strain-Induced Moire Superlattice Engineering in Twisted Hexagonal Boron Nitride
Bynatalierbaggett March 12, 2025

Taehyung KimKyung Hee University, Seoul, Republic of Korea _______________________________________ Twisted hexagonal boron nitride (hBN) heterostructures offer exceptional advantages in nanoscale ferroelectric control, enabling tunable moiré potentials and strain-modulated interfacial phenomena. This work demonstrates the direct visualization of strain-induced moiré superlattices and twirled domain architectures at interfacial bubbles via Kelvin probe force microscopy (KPFM). Local strain…

Photophysics of Quantum Defects in Hexagonal Boron Nitride
Bynatalierbaggett March 4, 2025March 4, 2025

Sanjay BehuraDepartment of Physics, San Diego State University, San Diego, CA, USA _______________________________________ Spin defect-based quantum light sources hosted on the surface of the material in contrast to the defects buried within the bulk of the material is promising for quantum information science. Atom-thin van der Waals quantum materials are truly surfaces and they have…

Microscopic model for optically addressable spin defect pairs in hBN
BySarah Ross March 2, 2025March 2, 2025

Viktor IvádyEötvös Loránd University – Budapest, Hungary_______________________________________ Optically detected magnetic resonance (ODMR) signals without resolvable zero-field splitting have been observed in hexagonal boron nitride across a broad spectral range, yet their microscopic origin is still unrevealed. Recent studies suggest that charge-transfer-induced spin pairs involving common point defects could naturally explain the key experimental features. We…

Low Temperature Spectroscopy of hBN Quantum Emitters
BySarah Ross March 2, 2025March 2, 2025

Mouli HazraTechnical University of Munich – Munich, Germany_______________________________________ Hexagonal boron nitride (hBN) is known to host a diverse range of high-quality single-photon emitters (SPEs), establishing its potential as a promising material for quantum technology applications. For these emitters to be used in practice, their spatial localisation and emission wavelengths must be precisely controlled. In this…

Gate-tunable polariton reflection in hBN-graphene heterostructures
BySarah Ross March 2, 2025

Siyuan DaiAuburn University – Auburn, Alabama, USA_______________________________________ The variation of optical momentum determines light propagation across material interfaces. Evident momentum mismatch at the two sides of the interface results in inefficient energy transfer due to the lack of phase matching, thereby causing light reflection or scattering. In this work, we demonstrate an electrically tunable polaritonic…

Molecular beam epitaxy of boron nitride arsenide highly mismatched alloys, feasibility studies
BySarah Ross March 1, 2025

Sergei NovikovUniversity of Nottingham – Nottingham, United Kingdom _______________________________________ The last decades have seen very rapid theoretical and experimental progress in studies of group III-N-V highly mismatched alloys (HMAs). HMAs are a class of semiconductor alloys whose constituents are distinctly different in terms of size, ionicity and/or electronegativity. The unusually strong dependence of the fundamental…

The Interaction between Diamond NV Centers and Boron Vacancies in hBN
BySarah Ross March 1, 2025March 2, 2025

Huan ZhaoOak Ridge National Laboratory – Oak Ridge, Tennessee, USA_______________________________________ Nitrogen-vacancy (NV) centers in diamond have long served as robust quantum sensors, capable of optically detecting magnetic fields at room temperature. Recently, boron vacancy centers in hexagonal boron nitride (hBN) have emerged as next-generation room-temperature quantum sensors, offering an out-of-plane quantization axis that is naturally…
