Ultrawide bandgap semiconductor heterojunction p-n diodes with distributed polarization doped p-type AlGaN layers on bulk AlN substrates

Posted by dbos Cornell

Kavli Affiliate: Grace Xing | First 5 Authors: Shivali Agrawal, Len van Deurzen, Jimy Encomendero, Joseph E. Dill, Hsin Wei | Summary: Ultrawide bandgap heterojunction p-n diodes with polarization-induced AlGaN p-type layers are demonstrated using plasma-assisted molecular beam epitaxy on bulk AlN substrates. Current-voltage characteristics show a turn on voltage of $V_{text{bi}}approx5.5$ V, a minimum […]

Resilience-driven neural synchrony during naturalistic movie watching: an ultra-high field fMRI study

Posted by dbos NTNU

Kavli Affiliate: Maryam Ziaei | Authors: Shuer Ye, Leona Rahel Batz, Jain Jain, Alireza Salami and Maryam Ziaei | Summary: Sharing others’ emotional states may facilitate the understanding of their well-being characteristics, such as resilience. Despite increasing attention given to resilience for its role in maintaining mental health, the intricacies of its underlying neural correlates […]

A unified accretion disc model for supermassive black holes in galaxy formation simulations: method and implementation

Posted by dbos Cambridge

Kavli Affiliate: Debora Sijacki | First 5 Authors: Sophie Koudmani, Rachel S. Somerville, Debora Sijacki, Martin A. Bourne, Yan-Fei Jiang | Summary: It is well established that supermassive black hole (SMBH) feedback is crucial for regulating the evolution of massive, if not all, galaxies. However, modelling the interplay between SMBHs and their host galaxies is […]

Precise Estimate of Charged Higgsino/Wino Decay Rate

Posted by dbos Tokyo

Kavli Affiliate: Satoshi Shirai | First 5 Authors: Masahiro Ibe, Yuhei Nakayama, Satoshi Shirai, , | Summary: Higgsinos and Winos in the supersymmetric Standard Model are prime candidates for dark matter due to their weakly interacting nature. The mass differences between their charged components (charginos) and neutral components (neutralinos) become degenerate when other superparticles are […]
