Kavli Affiliate: Jie Shan | First 5 Authors: Zhengchao Xia, Yihang Zeng, Bowen Shen, Roei Dery, Kenji Watanabe | Summary: The chemical potential u of an electron system is a fundamental property of a solid. A precise measurement of u plays a crucial role in understanding the electron interaction and quantum states of matter. However, […]
Kavli Affiliate: Zhiting Tian | First 5 Authors: Abhijit Biswas, Rui Xu, Joyce Christiansen-Salameh, Eugene Jeong, Gustavo A. Alvarez | Summary: Boron nitride (BN) is an exceptional material and among its polymorphs, two-dimensional (2D) hexagonal and three-dimensional (3D) cubic BN (h-BN and c-BN) phases are most common. The phase stability regimes of these BN phases […]

Seed treatment by nanomaterials is a cost-effective and environmentally-friendly solution for environmental stress mitigation in crop plants. Here, 56 seed nanopriming treatments are used to […]
Kavli Affiliate: Nicole A. Benedek | First 5 Authors: Anita Verma, Denis Golež, Oleg Yu. Gorobtsov, Kelson Kaj, Ryan Russell | Summary: Technology moves towards ever faster switching between different electronic and magnetic states of matter. Manipulating properties at terahertz rates requires accessing the intrinsic timescales of electrons (femtoseconds) and associated phonons (10s of femtoseconds […]
Kavli Affiliate: Nicole A. Benedek | Summary:Technology moves towards ever faster switching between different electronic and magnetic states of matter. Manipulating properties at terahertz rates requires accessing the intrinsic timescales of electrons (femtoseconds) and associated phonons (10s of femtoseconds to few picoseconds), which is possible with short-pulse photoexcitation. Yet, in many Mott insulators, the electronic […]
Kavli Affiliate: Jie Shan | First 5 Authors: Zui Tao, Bowen Shen, Wenjin Zhao, Nai Chao Hu, Tingxin Li | Summary: The spin Hall effect (SHE), in which electrical current generates transverse spin current, plays an important role in spintronics for the generation and manipulation of spin-polarized electrons. The phenomenon originates from spin-orbit coupling. In […]
Kavli Affiliate: Farhan Rana | First 5 Authors: Jimy Encomendero, Vladimir Protasenko, Farhan Rana, Debdeep Jena, Huili Grace Xing | Summary: The recent demonstration of resonant tunneling transport in nitride semiconductors has led to an invigorated effort to harness this quantum transport regime for practical applications. In polar semiconductors, however, the interplay between fixed polarization […]
Kavli Affiliate: Nicholas L. Abbott | First 5 Authors: Apoorva Jain, Soumyamouli Pal, Nicholas L. Abbott, Rong Yang, | Summary: The ability to synthesize shape-controlled polymer particles will benefit a wide range of applications including targeted drug delivery and metamaterials with reconfigurable structures, but existing synthesis approaches are commonly multistep and limited to a narrow […]
Kavli Affiliate: Nicholas L. Abbott | Summary:The ability to synthesize shape-controlled polymer particles will benefit a wide range of applications including targeted drug delivery and metamaterials with reconfigurable structures, but existing synthesis approaches are commonly multistep and limited to a narrow size/shape range. Using a novel single-step synthesis technique, a variety of shapes including nanospheres, […]
Kavli Affiliate: Gregory D. Fuchs | First 5 Authors: Yanyou Xie, Hil Fung Harry Cheung, Gregory D. Fuchs, , | Summary: In this work, we develop a nanoscale magnetic field sensor based on a spin-Hall nano-oscillator (SHNO) device. We fabricate constriction-based SHNO devices using Ni$_{81}$Fe$_{19}$/Au$_{0.25}$Pt$_{0.75}$ bilayer and use them to demonstrate quasi-DC sensing up to […]
