چکیده
Local manipulation of the defect structures in 2D semiconducting transition metal dichalcogenide (2D TMD) opens rich research avenues harnessing their unique optoelectronic properties, where reliable structure formation methods are highly desirable. Here, concept optical soldering (OS) on few-layer MoS2 to form site-selective with induced photoluminescence (PL) is proposed and demonstrated. OS initiated by heating top layer elevate local temperature above melting point underlying indium-tin-oxide nanoparticles (ITO-NPs). In turn, thermally deformed ITO-NPs pull down substrate, forming OS-induced optically irradiated region. The a show bright PL, which can be manipulated peak positions varying incident power irradiation time. facile method for patterning properties while requiring low incidence (≈2.5 mW) fast process time (≈1 s), beneficial development TMD material-based applications.

Defect Induced Faults in MOS Circuits
A strategy for modeling spot defect induced faults by their corresponding boolean functions is developed. The presented strategy is based on the principle of local conduction path analysis. This way of modeling is much more general in the sense that all kinds of faults are unified by one concept, the boolean function. In this way testing related applications can be done efficiently and can main...
متن کاملMagneto-Optical Study of Defect Induced Sharp Photoluminescence in LaAlO3 and SrTiO3
Strongly correlated electronic systems such as Transition Metal Oxides often possess various mid-gap states originating from intrinsic defects in these materials. In this paper, we investigate an extremely sharp Photoluminescence (PL) transition originating from such defect states in two widely used perovskites, LaAlO3 and SrTiO3. A detailed study of the PL as a function of temperature and magn...

متن کاملDefect Induced Structure Formation in the Early Universe
When describing the early universe as an FRW metric and being filled with perfect fluids, there is no first principle understanding of structure formation. Instead, at high temperatures one must describe the matter as a quantum field theory. As the universe expands, this field theory will undergo phase transitions, and the possibility for topological defects arise. This paper will discuss how t...
متن کاملDefect-Induced Photoluminescence Blinking of Single Epitaxial InGaAs Quantum Dots
Here we report two types of defect-induced photoluminescence (PL) blinking behaviors observed in single epitaxial InGaAs quantum dots (QDs). In the first type of PL blinking, the "off" period is caused by the trapping of hot electrons from the higher-lying excited state (absorption state) to the defect site so that its PL rise lifetime is shorter than that of the "on" period. For the "off" peri...
