The frequency dependence of the complex electrical impedance ( Z* ) and modulus ( M* ) of two types of semiconducting materials, is studied. These are Cu 5 In 9 Se 16 (CIS), an ordered defect compound of the I-III-VI 2 family and a novel bentonite clay system which is insulator at room...

In a small-area semiconductor the activity of just one single trap reveals discrete switching, which is usually referred to as a random telegraph signal (RTS). Such RTSs are attributed to the capture and emission of charge carriers by a single active trap located in an oxide layer. This activity...

We calculate dwell time of electron in magnetically and electrically confined semiconductor nanostructure (MECSN) that is fabricated in experiments by patterning a ferromagnetic (FM) stripe and a Schottky-metal (SM) stripe on the surface of InAs/AlxIn1-xAs. Spin-dependent dwell time is revealed...

Abstract ; Nickel oxide (NiO x ) is one of the most promising inorganic hole transport layers for perovskite solar cells (PSCs), due to its low cost, high hole mobility, and superior stability. However, the mismatched energy level and undesirable chemical reaction at the NiO x /perovskite...

Fluoride and silica contamination in water is a worldwide issue due to the wastewater discharge from semiconductor industry. Coagulation-ultrafiltration (UF) process is commonly used to treat semiconductor wastewater, but requires excessive amounts of coagulant/flocculant. In this study, an...

The semiconductor industry stands at the center of the intensifying Sino-American trade conflict. Employing a multi-country, multi-sector general equilibrium modeling framework with imperfect competition and heterogeneous firms, we perform qualitative and quantitative analyses of protectionist...

We map companies belonging to the semiconductor value chain at the world level and investigate the turnover of the companies by jurisdiction of their ultimate owner. Total turnover for the top-10 companies, with respect to revenue, among the manufacturers of semiconductors amounts to 266 Billion...

Semiconductors are at the heart of the U.S.-China technology hegemony competition under the administration of U.S. president Joe Biden. Conflicts between the U.S. and China over the semiconductor supply chain are intensifying as Biden signed an executive order on February 24, 2021, ordering the...
