Ambient‐Stable Transparent P‐Type CuI Transistors Via Room‐Temperature Pulsed Laser Deposition

Advanced Functional Materials, EarlyView.
An in situ PLD fabricated AlOx${\rm AlO}_x$/CuI/AlOx${\rm AlO}_x$ sandwich structure enables stable CuI TFTs with a field‐effect mobility of 2.3 ±$\pm$ 0.7 cm2${\rm cm}^{2}$ V−1${\rm V}^{-1}$ s−1${\rm s}^{-1}$ and excellent ambient stability. Complementary inverters based on CuI:Rb and ZnO:Al exhibit rail‐to‐rail voltage transfer characteristics and an

Dopant Distribution in Ga‐Implanted CdO—A Correlative Microscopy and Molecular Dynamics Study

Advanced Functional Materials, EarlyView.
This work demonstrates that ion implantation offset angle could modulate carrier concentration and mobility in cadmium oxide thin films. Combining correlative microscopy workflow and molecular dynamics simulations, this study reveals the control of interfacial cluster density with tailoring implantation angles, and the optimum offset angle that ...

Approximation Algorithms for Facility Location Problems [PDF]

, 2000
One of the most flourishing areas of research in the design and analysis of approximation algorithms has been for facility location problems. In particular, for the metric case of two simple models, the uncapacitated facility location and the k-median problems, there are now a variety of techniques that yield constant performance guarantees.
