Temperature dependent photoluminescence of an In(Ga)As/GaAs quantum dot system with different areal density

Journal of Physics D Applied Physics (2010)

Xiaolong Zhou Y H Chen J Q Liu Caihong Jia Guanyu Zhou

We have systematically studied the temperature dependent photoluminescence of a self-assembled In(Ga)As/GaAs quantum dot (QD) system with different areal densities from ∼10 9 to ∼10 11 cm −2 . Different carrier channels are revealed experimentally and confirmed theoretically via a modified carrier equation model considering a new carrier transfer channel, i.e. continuum states (CS). The wetting layer is demonstrated to be the carrier quenching channel for the low-density QDs but the carrier transfer channel for the high-density QDs. In particular, for the InGaAs/GaAs QDs with a medium density of ∼10 10 cm −2 , the CS is verified to be an additional carrier transfer channel in the low temperature regime of 10–60 K, which is studied in detail via our models. The possible carrier channels that act on different temperature regimes are further discussed, and it is demonstrated that density is not a crucial factor in determining the carrier lateral coupling strength.

Microplastics, as a novel type of environmental pollutant, have attracted notable attention in environmental research due to their widespread distribution and potential biological toxicity. Drinking water treatment plants play a crucial role in ensuring the safety of the water supply, with a particular focus on the removal efficiency of microplastics in drinking water treatment plants. Different treatment processes in water plants exhibit various removal efficiencies of microplastics and they operate through distinct removal mechanisms. To comprehensively analyze the removal efficiency and mechanism of microplastics in drinking water treatment plants, this study first examined the abundance and removal efficiency of microplastics of the influent and effluent of drinking water treatment plants. Subsequently, this study reviewed the removal efficiency and mechanism of four commonly used treatment processes： coagulation/flocculation/sedimentation, sand filtration, membrane filtration, and disinfection. The shortcomings and gaps in current studies were also pointed out. Finally, the assessment of microplastics abundance and human exposure in tap water was summarized and the future research direction was prospected from the perspectives of standardized sampling detection methods, nanoplastic detection, microplastics release in water supply systems, and risk assessment.

Weak magnetic field enhances the activation of peroxymonosulfate by ZnO@Fe₃O₄

RSC Advances (2018)

Haodi Zhao Jing Zhang Qian Ye Hao Xu Guanyu Zhou

The effect of weak magnetic field (WMF) on Acid Orange 7 (AO7) removal by ZnO@Fe3O4/peroxymonosulphate (PMS) was investigated. The results showed that the AO7 sequestration rate enhanced progressively to 0.14183 min-1 in the presence of WMF, approximately 3 times the 0.04966 min-1 in the absence of WMF. SO4˙-/SO5˙- and O2˙- radicals were generated from the decomposition of PMS catalyzed by ZnO@Fe3O4 causing the degradation of AO7. In addition, a weak magnetic field promoted the production of O2˙- radicals and transition of Fe3+ to Fe2+. Radical-pair theory was used in this study to describe the role of WMF and a possible reaction mechanism was derived. Based on that, the influence of magnetic field flux intensity, pH and the reusability of ZnO@Fe3O4 were investigated in this paper.

Predicting and Accelerating Nanomaterial Synthesis Using Machine Learning Featurization

Nano Letters (2024)

Christopher C. Price Yansong Li Guanyu Zhou Rehan Younas Siyang Zeng

Materials synthesis optimization is constrained by serial feedback processes that rely on manual tools and intuition across multiple siloed modes of characterization. We automate and generalize feature extraction of reflection high-energy electron diffraction (RHEED) data with machine learning to establish quantitatively predictive relationships in small sets (∼10) of expert-labeled data, saving significant time on subsequently grown samples. These predictive relationships are evaluated in a representative material system (W

Controlling the Pd Metal Contact Polarity to Trigonal Tellurium by Atomic Hydrogen‐Removal of the Native Tellurium Oxide

Advanced Materials Interfaces (2021)

Christopher M. Smyth Guanyu Zhou Adam T. Barton Robert M. Wallace Christopher L. Hinkle

Abstract Palladium (Pd) electrodes have enabled superior performance in Te‐based devices. Theory predicts strong Fermi level (EF) pinning near the Te valence band, which likely explains the predominant p ‐type conduction in Te transistors. The effects of the native TeOx on the contact polarity has not been explored. In this work, X‐ray and ultraviolet photoelectron spectra (XPS and UPS, respectively) reveal the native surface oxide de‐pins the EF between Pd and trigonal Te (t‐Te) and can reduce contact resistance of hole and electron contacts to Te for back end of line‐compatible complementary logic circuits. Atomic hydrogen reduces the native t‐Te oxide below the XPS detection limit, after which, the EF resides near the t‐Te conduction band edge. Therefore, an n ‐type band alignment is formed between Pd and t‐Te via an atomic hydrogen treatment. Furthermore, UPS shows the EF is pinned near the t‐Te conduction band edge. XPS indicates the formation of a PdTex intermetallic at the Pdt‐Te interface also affects the electrostatics of the interface. The concentration of PdTex is 40% higher when TeO x is removed from the t‐Te surface before Pd metallization, likely the root cause of the low (pinned) work function when the native oxide is absent.
