Epitaxial high-K AlBN barrier GaN HEMTs

Kavli Affiliate: Grace Xing | First 5 Authors: Chandrashekhar Savant, Thai-Son Nguyen, Kazuki Nomoto, Saurabh Vishwakarma, Siyuan Ma | Summary: We report a polarization-induced 2D electron gas (2DEG) at an epitaxial AlBN/GaN heterojunction grown on a SiC substrate. Using this 2DEG in a long conducting channel, we realize ultra-thin barrier AlBN/GaN high electron mobility transistors […]

Growth and characterization of single crystal cubic TaN and hexagonal Ta$_2$N films on c-plane Sapphire

Kavli Affiliate: Grace Xing | First 5 Authors: Anand Ithepalli, Amit Rohan Rajapurohita, Arjan Singh, Rishabh Singh, John Wright | Summary: Two single crystal phases of tantalum nitride were stabilized on c-plane sapphire using molecular beam epitaxy. The phases were identified to be $delta$-TaN with a rocksalt cubic structure and $gamma$-Ta$_2$N with a hexagonal structure. […]

Controllable Interlocking from Irregularity in Two-Phase Composites

Kavli Affiliate: Chiara Daraio | First 5 Authors: Chelsea Fox, Kyrillos Bastawros, Tommaso Magrini, Chiara Daraio, | Summary: Natural materials often feature a combination of soft and stiff phases, arranged to achieve excellent mechanical properties, such as high strength and toughness. Many natural materials have even independently evolved to have similar structures to obtain these […]

Atomic layer etching of niobium nitride using sequential exposures of O$_2$ and H$_2$/SF$_6$ plasmas

Kavli Affiliate: Austin J. Minnich | First 5 Authors: Azmain A. Hossain, Sela Murphy, David S. Catherall, Anthony J. Ardizzi, Austin J. Minnich | Summary: Niobium nitride (NbN) is a metallic superconductor that is widely used for superconducting electronics due to its high transition temperature ($T_c$) and kinetic inductance. Processing-induced damage negatively affects the performance […]
