Twist-Reconfigurable van der Waals Moiré Photonic Crystals
Hugo Quard, Jiyun Kim, Anastasiia Zalogina +7
Moiré photonics has emerged as a fascinating concept to design and in situ control of the optical bands. Moiré enabled light localisation arises from the relative twist between per…
Near-UV Single-Pixel Imaging with All-Inorganic Lead-Free Perovskite
Jiyun Kim, Xinyang Yu, Zijian Feng +4
Single-pixel imaging (SPI) is a powerful computational imaging technology that reconstructs spatial information from sequentially encoded optoelectrical signals without pixelated d…
In-situ Silicon Doped hBN by High-Temperature Molecular Beam Epitaxy Enables Single Photon Emission
Jiyun Kim, Nika Teran, Juliette Plo +8
Hexagonal boron nitride (hBN) has emerged as a leading host for optically active quantum defects. Yet introduction of specific impurity species other than carbon remains unexplored…
Harnessing Non-Boltzmann Steady States in Lanthanide Nanocrystals for Mid-Infrared Optoelectronics
Xinyang Yu, Yin Huang, Karin Yamamura +15
Converting mid-infrared (MIR) radiation to visible or near-infrared wavelengths is essential for imaging and sensing, yet achieving sensitive, low-power, and scalable detection rem…
