Unveiling the Shape Evolution and Halide-Ion-Segregation in Blue-Emitting Formamidinium Lead Halide Perovskite Nanocrystals Using an Automated Microfluidic Platform

19-Jan-2018 | Ioannis Lignos; Loredana Protesescu; Dilara Börte Emiroglu; Richard Maceiczyk; Simon Schneider; Maksym V. Kovalenko; ..., Nano Letters, 2018

Hybrid organic–inorganic perovskites and in particular formamidinium lead halide (FAPbX3, X = Cl, Br, I) perovskite nanocrystals (NCs) have shown great promise for their implementation in optoelectronic devices. Specifically, the Br and I counterparts have shown unprecedented photoluminescence ...

Quantum Control of Graphene Plasmon Excitation and Propagation at Heaviside Potential Steps

19-Jan-2018 | Dongli Wang; Xiaodong Fan; Xiaoguang Li; Siyuan Dai; Laiming Wei; Wei Qin; Fei Wu; Huayang Zhang; Zeming Qi; Changga ..., Nano Letters, 2018

Quantum mechanical effects of single particles can affect the collective plasmon behaviors substantially. In this work, the quantum control of plasmon excitation and propagation in graphene is demonstrated by adopting the variable quantum transmission of carriers at Heaviside potential steps as a ...

Spin–Orbit Torques in NbSe2/Permalloy Bilayers

19-Jan-2018 | Marcos H. D. Guimarães; Gregory M. Stiehl; David MacNeill; Neal D. Reynolds; Daniel C. Ralph, Nano Letters, 2018

We present measurements of current-induced spin–orbit torques generated by NbSe2, a fully metallic transition-metal dichalcogenide material, made using the spin-torque ferromagnetic resonance (ST-FMR) technique with NbSe2/Permalloy bilayers. In addition to the out-of-plane Oersted torque expected ...

Impact of Nanoporosity on Hydrocarbon Transport in Shales’ Organic Matter

18-Jan-2018 | Amaël Obliger; Franz-Josef Ulm; Roland Pellenq, Nano Letters, 2018

In a context of growing attention for shale gas, the precise impact of organic matter (kerogen) on hydrocarbon recovery from unconventional reservoirs still has to be assessed. Kerogen’s microstructure is characterized by a very disordered pore network that greatly affects hydrocarbon transport. ...

Electrochemical Reaction Mechanism of the MoS2 Electrode in a Lithium-Ion Cell Revealed by in Situ and Operando X-ray Absorption Spectroscopy

18-Jan-2018 | Liang Zhang; Dan Sun; Jun Kang; Jun Feng; Hans A. Bechtel; Lin-Wang Wang; Elton J. Cairns; Jinghua Guo, Nano Letters, 2018

As a typical transition metal dichalcogenide, MoS2 offers numerous advantages for nanoelectronics and electrochemical energy storage due to its unique layered structure and tunable electronic properties. When used as the anode in lithium-ion cells, MoS2 undergoes intercalation and conversion ...

Switchable Single-Mode Perovskite Microlasers Modulated by Responsive Organic Microdisks

17-Jan-2018 | Jinyang Zhao; Yongli Yan; Cong Wei; Wei Zhang; Zhenhua Gao; Yong Sheng Zhao, Nano Letters, 2018

Miniaturized lasers with high spectra purity and switchable output are of crucial importance for various ultracompact photonic devices. However, it still remains a great challenge to simultaneously control the wavelength and mode purity of microscale lasers due to the insensitive response of ...

Solution to the Hole-Doping Problem and Tunable Quantum Hall Effect in Bi2Se3 Thin Films

17-Jan-2018 | Jisoo Moon; Nikesh Koirala; Maryam Salehi; Wenhan Zhang; Weida Wu; Seongshik Oh, Nano Letters, 2018

Bi2Se3, one of the most widely studied topological insulators (TIs), is naturally electron-doped due to n-type native defects. However, many years of efforts to achieve p-type Bi2Se3 thin films have failed so far. Here, we provide a solution to this long-standing problem, showing that the main ...

Atom-Dependent Edge-Enhanced Second-Harmonic Generation on MoS2 Monolayers

17-Jan-2018 | Kuang-I Lin; Yen-Hung Ho; Shu-Bai Liu; Jian-Jhih Ciou; Bo-Ting Huang; Christopher Chen; Han-Ching Chang; Chien-Liang ..., Nano Letters, 2018

Edge morphology and lattice orientation of single-crystal molybdenum disulfide (MoS2) monolayers, a transition metal dichalcogenide (TMD), possessing a triangular shape with different edges grown by chemical vapor deposition are characterized by atomic force microscopy and transmission electron ...
