Semiconducting Black Phosphorus: Synthesis, Transport Properties and Electronic Applications
Han Liu, Yuchen Du, Yexin Deng +1
Phosphorus is one of the most abundant elements preserved in earth, constructing with a fraction of ~0.1% of the earth crust. In general, phosphorus has several allotropes. The two…
Chloride Molecular Doping Technique on 2D Materials: WS2 and MoS2
Lingming Yang, Kausik Majumdar, Han Liu +8
Low-resistivity metal-semiconductor (M-S) contact is one of the urgent challenges in the research of 2D transition metal dichalcogenides (TMDs). Here, we report a chloride molecula…
Temporal and Thermal Stability of Al2O3-passivated Phosphorene MOSFETs
Xi Luo, Yaghoob Rahbarihagh, James C. M. Hwang +3
This letter evaluates temporal and thermal stability of a state-of-the-art few-layer phosphorene MOSFET with Al2O3 surface passivation and Ti/Au top gate. As fabricated, the phosph…
Two-Dimensional TaSe2 Metallic Crystals: Spin-Orbit Scattering Length and Breakdown Current Density
Adam T. Neal, Yuchen Du, Han Liu +1
We have determined the spin-orbit scattering length of two-dimensional layered 2H-TaSe2 metallic crystals by detailed characterization of the weak anti-localization phenomena in th…
Device Perspective for Black Phosphorus Field-Effect Transistors: Contact Resistance, Ambipolar and Scaling
Yuchen Du, Han Liu, Yexin Deng +1
Although monolayer black phosphorus (BP) or phosphorene has been successfully exfoliated and its optical properties have been explored, most of electrical performance of the device…
Black Phosphorus-Monolayer MoS2 van der Waals Heterojunction P-N Diode
Yexin Deng, Zhe Luo, Nathan J. Conrad +7
Phosphorene, an elemental 2D material, which is the monolayer of black phosphorus, has been mechanically exfoliated recently. In its bulk form, black phosphorus shows high carrier…
