OH absorption in on-chip high-Q resonators
Kavli Affiliate: Kerry J. Vahala | First 5 Authors: Lue Wu, Maodong Gao, Jin-Yu Liu, Hao-Jing Chen, Kellan Colburn | Summary: Thermal silica is a common dielectric used in all silicon-photonic circuits. And bound hydroxyl ions (Si-OH) can provide a significant component of optical loss in this material on account of the wet nature of […]

Designing transparent conductors using forbidden optical transitions
Kavli Affiliate: Kristin A. Persson | Authors: Rachel Woods-Robinson, Yihuang Xiong, Jimmy-Xuan Shen, Nicholas Winner, Matthew K. Horton, Mark Asta, Alex M. Ganose, Geoffroy Hautier, Kristin A. Persson | Summary: Many semiconductors present weak or forbidden transitions at their fundamental band gaps, inducing a widened region of transparency. This occurs in high-performing n-type transparent conductors […]

Designing transparent conductors using forbidden optical transitions
Kavli Affiliate: Kristin A. Persson | First 5 Authors: Rachel Woods-Robinson, Yihuang Xiong, Jimmy-Xuan Shen, Nicholas Winner, Matthew K. Horton | Summary: Many semiconductors present weak or forbidden transitions at their fundamental band gaps, inducing a widened region of transparency. This occurs in high-performing n-type transparent conductors (TCs) such as Sn-doped In2O3 (ITO), however thus […]

Visualizing the atomic-scale origin of metallic behavior in Kondo insulators
Kavli Affiliate: J. C. Seamus Davis | First 5 Authors: Harris Pirie, Eric Mascot, Christian E. Matt, Yu Liu, Pengcheng Chen | Summary: A Kondo lattice is often electrically insulating at low temperatures. However, several recent experiments have detected signatures of bulk metallicity within this Kondo insulating phase. Here we visualize the real-space charge landscape […]

Non-planar snake gaits: from Stigmatic-starts to Sidewinding
Kavli Affiliate: L. Mahadevan | First 5 Authors: N. Charles, R. Chelakkot, M. Gazzola, B. Young, L. Mahadevan | Summary: Of the vast variety of animal gaits, one of the most striking is the non-planar undulating motion of a sidewinder. But non-planar gaits are not limited to sidewinders. Here we report a new non-planar mode […]

Giant spin Hall effect in AB-stacked MoTe2/WSe2 bilayers
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 […]

Stabilizing the inverted phase of a WSe$_2$/BLG/WSe$_2$ heterostructure via hydrostatic pressure
Kavli Affiliate: Srijit Goswami | First 5 Authors: Máté Kedves, Bálint Szentpéteri, Albin Márffy, Endre Tóvári, Nikos Papadopoulos | Summary: Bilayer graphene (BLG) was recently shown to host a band-inverted phase with unconventional topology emerging from the Ising-type spin–orbit interaction (SOI) induced by the proximity of transition metal dichalcogenides with large intrinsic SOI. Here, we […]
