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

Bifurcations of composite-cavity modes in multi-stripe laser arrays [PDF]
, 2008 We consider a semiconductor laser device, where the active region consists of parallel stripes in the longitudinal direction. In the composite cavity model, the stripes are coupled via the transversal modes of the entire compound laser device.
