Engineering the electronic and magnetic properties of d0 2D dichalcogenide materials through vacancy doping and lattice strains

09-Feb-2016 | Lei Ao; Anh Pham; Haiyan Xiao; Xiaotao Zu; Sean Li, Physical Chemistry Chemical Physics, 2016

We have systematically investigated the effects of different vacancy defects in 2D d0 materials SnS2 and ZrS2 using first principles calculations. The theoretical results show that single cation vacancy and vacancy complex like V-SnS6 can induce large magnetic moments (3 μB – 4 μB) in these ...

Dual-doping to suppress cracking in spinel LiMn2O4: a joint theoretical and experimental study

09-Feb-2016 | zhifeng zhang; Zhenlian Chen; heng ren; Mu Pan; Guangjin Wang; Lingli Xiao; Kuicheng Wu; Liutao Zhao; Jianqing Yang; ..., Physical Chemistry Chemical Physics, 2016

Electrochemical cycling stabilities were compared for undoped and Al/Co dual-doped spinel LiMn2O4 synthesized by solid state reactions. We observed the suppression of particle fracture in Al/Co dual-doped LiMn2O4 during charging/ discharging cycling and its distinguishable particle morphology ...

Interplay between Steps and Oxygen Vacancies on Curved TiO2(110)

04-Feb-2016 | Luis A. Miccio; Martin Setvin; Moritz Müller; Mikel Abadía; Ignacio Piquero; Jorge Lobo-Checa; Frederik Schiller; Ce ..., Nano Letters, 2016

A vicinal rutile TiO2(110) crystal with a smooth variation of atomic steps parallel to the [1–10] direction was analyzed locally with STM and ARPES. The step edge morphology changes across the samples, from [1–11] zigzag faceting to straight [1–10] steps. A step-bunching phase is attributed to an ...

Tuning the carrier concentration using Zintl chemistry in Mg3Sb2 and, its implications on thermoelectric figure-of-merit

03-Feb-2016 | Aman Bhardwaj; N. S. Chauhan; Shobhit Goel; Vijeta Singh; Jiji Pulikkotil; Senguttuvan TD; DINESH KUMAR MISRA, Physical Chemistry Chemical Physics, 2016

Abstract: Zintl compounds are potential candidates for efficient thermoelectric materials, because they are typically small band gap semiconductors. In addition, such compounds allow fine tuning of carrier concentration by chemical doping for the optimization of thermoelectric performance. ...

Novel microwave plasma‐assisted CVD reactor for diamond delta doping

02-Feb-2016 | A. L. Vikharev, A. M. Gorbachev, M. A. Lobaev, A. B. Muchnikov, D. B. Radishev, V. A. Isaev, V. V. Chernov, S. A. Bo ..., physica status solidi (RRL) - Rapid Research Letters, 2016

We report on building a novel chemical vapor deposition (CVD) reactor for diamond delta‐doping. The main features of our reactor are: a) the use of rapid gas switching system, (b) the reactor design providing the laminar gas flow. These features provide the creation of ultra‐sharp interfaces ...

Multiferroic broken by commensurate magnetic ordering

02-Feb-2016 | Guo Bao Li, Hao Zhang, Roxana Flacau, Xin Du, Pascal Manuel, Junzhuang Cong, Young Sun, Junliang Sun, Sihai Yang, Fu ..., ChemPhysChem, 2016

TbMnO3 is an important multiferroic showing strong coupling between magnetic and ferroelectric orderings. Incommensurate magnetic ordering is suggested to be vital for this coupling in TbMnO3, which can be modified by doping at the site of Tb and/or Mn. Our study shows that a self‐doped solid ...

Emerging drugs affecting skeletal muscle function and mitochondrial biogenesis – Potential implications for sports drug testing programs

02-Feb-2016 | Mario Thevis, Wilhelm Schänzer, Rapid Communications in Mass Spectrometry, 2016

Rationale A plethora of compounds potentially leading to drug candidates that affect skeletal muscle function and, more specifically, mitochondrial biogenesis, has been under (pre)clinical investigation for rare as well as more common diseases. Some of these compounds could be the object of ...

Photoluminescence, Structural, and Electrical Properties of Erbium‐Doped Na0.5Bi4.5Ti4O15 Ferroelectric Ceramics

01-Feb-2016 | Xingan Jiang, Xiangping Jiang, Chao Chen, Na Tu, Yunjing Chen, Banchao Zhang, Journal of the American Ceramic Society, 2016

Structural, electrical, and up‐conversion (UC) properties of Na0.5Bi4.5‐xErxTi4O15 (NBT–xEr3+) (0.00 3+ contents (x). The average values of grain size were found to slightly decrease with increasing x. Raman spectroscopy revealed that (Bi2O2)2+ layers remained unaffected in the modified ...

Gate-Tunable Dirac Point of Molecular Doped Graphene

01-Feb-2016 | Pablo Solís-Fernández; Susumu Okada; Tohru Sato; Masaharu Tsuji; Hiroki Ago, ACS Nano, 2016

Control of the type and density of charge carriers in graphene is essential for its implementation into various practical applications. Here, we demonstrate the gate-tunable doping effect of adsorbed piperidine on graphene. By gradually increasing the amount of adsorbed piperidine, the graphene ...

Intraband Luminescence from HgSe/CdS Core/Shell Quantum Dots

01-Feb-2016 | Zhiyou Deng; Philippe Guyot-Sionnest, ACS Nano, 2016

HgSe/CdS core/shell CQD are synthesized, and the changes in the optical absorption and luminescence are investigated. While HgSe quantum dots are naturally n-doped after synthesis, both as colloidal solutions and as films, the HgSe/CdS core/shell dots in solution lose the n-doping, as seen from ...
