XHEMTs on Ultrawide Bandgap Single-Crystal AlN Substrates

Posted by dbos Cornell, This Week: Nanoscience

Kavli Affiliate: Grace Xing | First 5 Authors: Eungkyun Kim, Yu-Hsin Chen, Naomi Pieczulewski, Jimy Encomendero, David Anthony Muller | Summary: AlN has the largest bandgap in the wurtzite III-nitride semiconductor family, making it an ideal barrier for a thin GaN channel to achieve strong carrier confinement in field-effect transistors, analogous to silicon-on-insulator technology. Unlike […]

Optimized cerebral blood flow measurement in speckle contrast optical spectroscopy via refinement of noise calibration

Posted by dbos Caltech, This Week: Nanoscience

Kavli Affiliate: Changhuei Yang | First 5 Authors: Ninghe Liu, Yu Xi Huang, Simon Mahler, Changhuei Yang, | Summary: Speckle contrast optical spectroscopy (SCOS) offers a non-invasive and cost-effective method for monitoring cerebral blood flow (CBF). However, extracting accurate CBF from SCOS necessitates precise noise pre-calibration. Errors from this can degrade CBF measurement fidelity, particularly […]
