MoS/AlScN negative capacitance field-effect transistors
Seunguk Song, Kwan-Ho Kim, Srikrishna Chakravarthi +6
AlScN (AlScN) has gained attention for its outstanding ferroelectric properties, including a high coercive field and high remnant polarization. Although AlScN-bas…
Exciton Confinement in Two-Dimensional, In-Plane, Quantum Heterostructures
Gwangwoo Kim, Benjamin Huet, Christopher E. Stevens +12
Two-dimensional (2D) semiconductors are promising candidates for optoelectronic application and quantum information processes due to their inherent out-of-plane 2D confinement. In…
Tailoring Exciton Dynamics in TMDC Heterobilayers in the Quantum Plasmonic Regime
Mahfujur Rahaman, Gwangwoo Kim, Kyung Yeol Ma +3
Control of excitons in transition metal dichalcogenides (TMDCs) and their heterostructures is fundamentally interesting for tailoring light-matter interactions and exploring their…
Strong Exciton-Photon Coupling in Large Area MoSe and WSe Heterostructures Fabricated from Two-Dimensional Materials Grown by Chemical Vapor Deposition
Daniel J. Gillard, Armando Genco, Seongjoon Ahn +11
Two-dimensional semiconducting transition metal dichalcogenides embedded in optical microcavities in the strong exciton-photon coupling regime may lead to promising applications in…
Infrared study of Large scale h-BN film and Graphene/h-BN heterostructure
Kwangnam Yu, Jiho Kim, Chul Lee +5
We synthesize a series of CVD h-BN films and perform critical infrared spectroscopic characterization. For high-temperature (HT, Temp = 1400 degrees) grown h-BN thin film only E1u-…
Quantum efficiency enhancement of bialkali photocathodes by an atomically thin layer on substrates
Hisato Yamaguchi, Fangze Liu, Jeffrey DeFazio +15
We report quantum efficiency (QE) enhancements in accelerator technology relevant antimonide photocathodes (K2CsSb) by interfacing them with atomically thin two-dimensional (2D) cr…
Resonantly hybridised excitons in moiré superlattices in van der Waals heterostructures
Evgeny M. Alexeev, David A. Ruiz-Tijerina, Mark Danovich +16
Atomically-thin layers of two-dimensional materials can be assembled in vertical stacks held together by relatively weak van der Waals forces, allowing for coupling between monolay…
Planar and van der Waals heterostructures for vertical tunnelling single electron transistors
Gwangwoo Kim, Sung-Soo Kim, Jonghyuk Jeon +18
Despite a rich choice of two-dimensional materials, which exists these days, heterostructures, both vertical (van der Waals) and in-plane, offer an unprecedented control over the p…
Imaging of interlayer coupling in van der Waals heterostructures using a bright-field optical microscope
Evgeny M. Alexeev, Alessandro Catanzaro, Oleksandr V. Skrypka +8
Vertically stacked atomic layers from different layered crystals can be held together by van der Waals forces, which can be used for building novel heterostructures, offering a pla…
