Transition-metal-doped WSe2 homojunctions for multifunctional logic and optoelectronic devices

Vu Khac Dat, Minh Chien Nguyen, Hai Phuong Duong, Tien Dat Ngo et autres

Control of carrier polarity in two-dimensional van der Waals semiconductors is essential for integrated electronic and optoelectronic systems. Here, we demonstrate that substitutional vanadium doping enables robust p-type modulation in multilayer WSe2 with pronounced thickness-dependent transport behavior. The transfer curve of V-doped …

Ultrafast switching and high-endurance nonvolatile memory enabled by intrinsic switchable polarization in semiconducting Janus monolayers

Ngoc Thanh Duong, Swathi Krishna, Minh Chien Nguyen, Hang Sik Kim et autres

The discovery of two-dimensional (2D) semiconducting ferroelectric (SFe) materials marks a pivotal step toward the realization of ferroelectric random-access memory. Despite their potential as ideal platforms for ultrafast switching and ultralow power consumption, SFe monolayers remain largely unexplored. In this work, we …

Synergistic Pyroelectric‐Bolometric Coupling in Tellurene Nanowire for Energy‐Efficient Artificial Vision

Thi Uyen Tran, Ngoc Thanh Duong, Ngoc Linh Nguyen, Nayeong Lee et autres

Thermal-energy harvesting, which converts heat into electrical signals, offers a promising route toward sustainable energy utilization. However, achieving efficient and stable thermal-electrical conversion in low-dimensional materials remains challenging. Although few-layer Tellurene (Te) exhibits pyroelectricity owing to intrinsic broken symmetry, this effect is …

Self‐Incandescent Heating‐Driven Microstructural Consolidation of Biscrolled Cu/CNT Yarns for Reduced Frequency‐Dependent AC Resistance

Feng Wang, Yoojoo Yun, Jung Hyun Ryu, Kyonghwa Song et autres

ABSTRACT Developing flexible conductors that combine high conductivity, stable MHz‐range electrical behavior, and mechanical durability remains a challenge. This is primarily because conventional bulk‐type metals suffer from frequency‐dependent AC‐resistance increases, while standard composites often exhibit poor interfacial integrity. Here, we address these …

Two-Dimensional Metal–Insulator Transition in Ultrathin VO 2 Nanosheets via Remote van der Waals Epitaxy

Suar Oh, Yuseong Heo, Young-Min Kim, Seong Chu Lim

Vanadium dioxide (VO 2 ) undergoes a rutile-to-monoclinic metal–insulator transition (MIT) at 340 K. Marked by abrupt resistivity changes of 10 4 –10 5 Ω·cm, this property has long attracted interest for electronic applications. However, when VO 2 is a few nanometers …

1,000,000 On/Off Ratio in Sub-1 nm Channel Length Carbon Nanotube/Monolayer MoS2/Carbon Nanotube Vertical Transistors

Van Dam, Ngoc Thanh Duong, Văn Tú Vũ, Minh Chien Nguyen et autres

Vertical field effect transistors (VFETs) using graphene and transition metal dichalcogenide (TMD) heterostructures are promising for downsizing the channel length to a monolayer TMD thickness of 0.65 nm. However, graphene/monolayer TMD/metal VFETs struggle with a low on/off ratio due to gate field …
