Holographic dictionary and defects in the bulk
We study the holographic dual of the AdS3 spacetime with a conical defect. We calculate the boundary two-point correlator using the holographic Gubser-Klebanov-Polyakov/Witten dictionary for a scalar field in the bulk.

We investigate the electrical characteristics of defects at the SiO2/Si interface, within the adjacent Si crystal, and through the depth profile of the bulk defect using three-dimensional deep-level transient spectroscopy (3D-DLTS).

Defect formation with bulk fields [PDF]
It has recently been realized that brane-antibrane annihilation (a possible explanation for ending inflation) may result in defect formation, due to the dynamics of the tachyon field. Studies of this possibility have generally ignored the interaction of the brane fields with fields in the bulk; recently it has been argued [1] that interactions with ...

Topological Defects and Bulk Melting of Hexagonal Ice [PDF]
We use classical molecular dynamics combined with the recently developed metadynamics method [A. Laio and M. Parrinello, Procs. Natl. Acad. Sci. USA 99, 20 (2002)] to study the process of bulk melting in hexagonal ice. Our simulations show that bulk melting is mediated by the formation of topological defects which preserve the coordination of the ...

A study of the performance of organometal trihalide perovskite solar cell due to defects in bulk CH3NH3PbI3 (MAPI) perovskite layer [PDF]
In this numerical simulation research, we have investigated device performances of p-i-n type organometal trihalide perovskite solar cell by introducing deep and shallow defects in the bulk halide perovskite layer. The organometal halide perovskite ...

Bulk and Surface Tunneling Hydrogen Defects in Alumina [PDF]
We perform ab initio calculations of hydrogen-based tunneling defects in alumina to identify deleterious two-level systems (TLS) in superconducting qubits. The defects analyzed include bulk hydrogenated Al vacancies, bulk hydrogen interstitial defects, and a surface OH rotor.

Vacancy defect distributions in bulk ZnO crystals [PDF]
We have used positron annihilation spectroscopy to study vacancy defects in ZnO single crystals grown by various methods from both commercial and academic sources. The combination of positron lifetime and Doppler broadening techniques with theoretical calculations provides the means to deduce both the identities and the concentrations of the ...

Artificial photosynthesis of H2O2 by TiO2-based semiconductors is a promising approach for H2O2 production. However, the efficiency of pristine TiO2 is still limited by rapid charge separation and low O2 adsorption capacity.

Applications of Photoluminescence Microscopy for Probing Bulk Defects in Silicon [PDF]
Global adoption of photovoltaics for power generation is expected to accelerate over the next decades due to increased concern regarding climate change and their reduced cost.
