Coherent phonon motions and ordered vacancy compound mediated quantum path interference in Cu-poor CuIn$_{x}$Ga$_{(1-x)}$Se$_2$ (CIGS) with attosecond transient absorption

Posted by dbos Berkeley

Kavli Affiliate: Peidong Yang | First 5 Authors: Hugo Laurell, Jonah R. Adelman, Elizaveta Yakovleva, Carl Hägglund, Kostiantyn Sopiha | Summary: In this study, coherent phonon motion is observed in bandgap excited CuIn$_{x}$Ga$_{(1-x)}$Se$_2$ (CIGS) utilizing extreme ultraviolet (XUV) attosecond transient absorption spectroscopy across the Se M$_{4,5}$ absorption edge. Two frequencies of coherent phonon motion are […]

Fentanyl reinforcement history has sex-specific effects on multi-step decision-making

Posted by dbos Hopkins

Kavli Affiliate: Patricia Janak | Authors: Eric Garr, Yifeng Cheng, Andy Dong and Patricia H. Janak | Summary: It is commonly thought that drug addiction involves a transition to habitual control of action, where the choice to consume drugs becomes automatized and reflects a failure to deliberate over possible negative outcomes. Determining whether the pursuit […]
