Detoxification of water by semiconductor photocatalysis [PDF]

, 2004
An overview of the use of semiconductor photocatalysis for water purification is given. The basic principles of semiconductor photocatalysis are described along with the current understanding of the underlying reaction mechanism(s) and how it fits in ...

Spin blockade at semiconductor/ferromagnet junctions

, 2007
We study theoretically extraction of spin-polarized electrons at nonmagnetic semiconductor/ferromagnet junctions. The outflow of majority spin electrons from the semiconductor into the ferromagnet leaves a cloud of minority spin electrons in the ...

Spin‐Gapless Semiconductors

Small, 2020
AbstractThe spin‐gapless semiconductors (SGSs) are a new class of zero‐gap materials which have fully spin polarized electrons and holes. They bridge the zero‐gap materials and the half‐metals. The band structures of the SGSs can have two types of energy dispersion: Dirac linear dispersion and parabolic dispersion.

Thermoreflectance Detection of Point Defects Resulting from Focused Ion Beam Milling

Advanced Engineering Materials, EarlyView.
Focused ion beam (FIB) milling is a common tool for nanoscale material processing, however irradiation damage, redeposition, and contamination can occur. We use several characterization tools to show FIB‐induced effects beyond 1 mm from the milled area.

Deep trap, laser activated image converting system [PDF]

, 1975
Receiving an optical image on the surface of a photoconducting semiconductor is presented, storing the image in deep traps of the semiconductor, and later scanning the semiconductor with a laser beam to empty the deep traps, thereby producing a video ...

Oxide Ceramic Large‐scale Integration Device for Putting the Brakes on Global Boiling Accelerated by Artificial Intelligence Age Computers

International Journal of Ceramic Engineering & Science
One factor that is considered to be a cause of global boiling, which is becoming a serious social problem, is the rapid progress and widespread use of artificial intelligence (AI).

Synthesis, Structure, Photoluminescence, Energy Transfer Mechanism and Band Gap of a Terbium-Mercury Complex with a 3-D Framework

Acta Chimica Slovenica, 2018
A novel terbium-mercury compound [Tb(IA)3(H2O)2(Hg2Cl4)]n·nHgCl2·nH2O (1, HIA = isonicotinic acid) was prepared via a hydrothermal reaction and structurally characterized through single-crystal X-ray diffraction technique.

Nanoindentation Criteria for Combinatorial Thin Film Libraries

Advanced Engineering Materials, EarlyView.
Thin‐film material libraries are compositional spreads used for screening composition‐structure‐property relationships. Nanoindentation is often used to characterize mechanical behavior across these systems, however variations in methodology are widespread.

Parity lifetime of bound states in a proximitized semiconductor nanowire [PDF]

, 2015
Quasiparticle excitations can compromise the performance of superconducting devices, causing high frequency dissipation, decoherence in Josephson qubits, and braiding errors in proposed Majorana-based topological quantum computers. Quasiparticle dynamics

Handbook of Establishing and Maintaining Oxygen‐Free Atmospheres

Advanced Engineering Materials, EarlyView.
This study presents a practical framework for creating oxygen‐free atmospheres at ambient pressure using silane‐doped inert gases. The results show that ultra‐low oxygen levels and strongly reduced water content can be achieved through controlled silane dosing, drying systems, and sensor monitoring.
