Dual-Mode Exciton Coupling in Epitaxially Registered Organic-Inorganic 2D Heterocrystals
Eunbeen Jeon, Kihyun Lee, Jieun Yeon +5
Two-dimensional (2D) heterocrystals comprising molecules and semiconductors can serve as an ideal platform for studying interfacial excitons and for future optoelectronic applicati…
Substrate-Mediated Persistent Photodoping in WSe2/hBN Field-Effect Transistors Enabled by Defect States in SiO2
Sung-Ha Kim, Seong-Yeon Lee, Tae-Jeong Kim +6
Photodoping plays an important role in determining the optoelectronic response of two-dimensional semiconductor devices; however, the origin of the responsible trap states remains…
Dielectric and gate metal engineering for threshold voltage modulation in enhancement mode monolayer MoS2 field effect transistors
Lixin Liu, Han Yan, Leyi Loh +8
Excellent gate electrostatics in field effect transistors (FETs) based on two-dimensional transition metal dichalcogenide (2D TMD) channels can dramatically decrease static power d…
Rewritable Complementary Nanoelectronics Enabled by Electron-Beam Programmable Ambipolar Doping
Qing Lan, Wenqing Song, Siyin Zhu +13
The ability to reversibly and site-selectively tune ambipolar doping in a single semiconductor is crucial for reconfigurable electronics beyond silicon, but remains highly challeng…
Graphene Heterostructure-Based Non-Volatile Memory Devices with Top Floating Gate Programming
Gabriel L. Rodrigues, Ana B. Yoshida, Guilherme S. Selmi +7
We present a graphene-based memory platform built on dual-gated field-effect transistors (GFETs). By integrating a lithographically defined metal patch directly atop the hexagonal…
Valley optoelectronics based on meta-waveguide photodetectors
Chi Li, Kaijian Xing, Wenhao Zhai +10
In transition metal dichalcogenides, the valley degree of freedom directly couples valley-polarised excitons - excited by circularly polarised light - to valley-dependent chiral ph…
