Vapor-phase grown ZnO crystals were investigated by means of DLTS measurements. The generation of defect center E4 subsequent to annealing in different ambients was monitored. By conducting electron irradiations with energies, where either both the Zn- and O-sublattice are damaged or according to [1] only the Zn-lattice, a chemical assignment to the defect centers E4 and E3 could be accomplished. ...... hiện toàn bộ
Structural phase transition induced by ion irradiation in the equilibrium immiscible Ag–Co systemApplied Physics A Solids and Surfaces - Tập 81 - Trang 1435-1439 - 2005
H.F. Yan, B.X. Liu
In the equilibrium immiscible Ag–Co system characterized by a large positive heat of formation (28 kJ/mol), interesting structural phase transitions were observed in Ag–Co multilayered films upon 200-keV xenon-ion irradiation at 300 K within a dose range of 5×1014 to 9×1015 Xe+/cm2. The formation of a new metastable HCP phase and observation of other structural phase transitions upon ion irradiati...... hiện toàn bộ
Femtosecond laser processing of fused silica and aluminum based on electron dynamics control by shaping pulse trainsApplied Physics A Solids and Surfaces - Tập 109 - Trang 679-684 - 2012
Ni Leng, Lan Jiang, Xin Li, Chuancai Xu, Pengjun Liu, Yongfeng Lu
The pulse train effects on femtosecond laser material processing are investigated from the viewpoint of electron dynamics on dielectrics with fused silica as a case study and metals with Al as a case study in air and water. During femtosecond laser (800 nm, 35 fs) pulse train (double pulses per train) processing of fused silica, a non-monotonic relationship between ablation size and pulse separati...... hiện toàn bộ
Self-powered low-range pressure sensor using biopolymer compositesApplied Physics A Solids and Surfaces - Tập 128 - Trang 1-9 - 2022
Nimitha Bhanu, M. E. Harikumar, Sudip K. Batabyal
The wearable, flexible, non-toxic, and biocompatible pressure sensors have gained a lot of interest in recent years due to the potential application of transducing physical phenomena like pressure and temperature into electrical signals. This paper presents a novel approach of using pectin–PEG–graphite (PPEGG) composite as a pressure sensing material that is biocompatible, self-powering, degradabl...... hiện toàn bộ
Interlayer coupling in [Er|Tb] superlatticesApplied Physics A Solids and Surfaces - Tập 74 - Trang s1517-s1519 - 2002

We report on interlayer coupling in [Ern(Er)|Tbn(Tb)] superlattices. By means of neutron diffraction, helix-like and conical magnetic structures are observed in an [Er20|Tb5] sample. These structures are correlated across terbium layers at low temperatures, where bulk terbium is ferromagnetic. Moreover, resonant X-ray magnetic scattering gives clear evidence that the 5d conduction band of terbium ...... hiện toàn bộ
The theoretical study of Rh single atom catalysts decorated C3N monolayer with N vacancy for CO oxidationsApplied Physics A Solids and Surfaces - Tập 129 - Trang 1-9 - 2023
Yanxing Zhang, Xinyang Gao
In this work, the single Rh atom anchored by N vacancy of C3N monolayer for CO oxidations has been studied by using first-principles calculations. The stability for a single Rh atom in N vacancy of C3N monolayer is detailed investigated. The sizeable binding energy and diffusion barrier of the Rh atom in the N vacancy and the ab initial molecule dynamic simulations at 400 K all verify that the Rh ...... hiện toàn bộ
Vertical electrical conduction in pentacene polycrystalline thin films mediated by Au-induced gap states at grain boundariesApplied Physics A Solids and Surfaces - Tập 95 - Trang 225-232 - 2009

Vertical electrical conduction in Au/(polycrystal-line pentacene)/Al diode structures and the influence of the kinetic energy of incident Au atoms on the conduction property have been comprehensively studied using current–voltage–temperature (I–V–T) measurements, ultraviolet photoelectron spectroscopy (UPS), atomic-force-microscope (AFM) current imaging, etc. In the I–V characteristics, a symmetri...... hiện toàn bộ
