Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Yu Gu, Huan Yan, Yantong Wang, Mianxiong Dong | Summary: Vital sign (breathing and heartbeat) monitoring is essential for patient care and sleep disease prevention. Most current solutions are based on wearable sensors or cameras; however, the former could affect sleep quality, while the latter […]
Kavli Affiliate: Naomi S. Ginsberg | First 5 Authors: Hannah L. Weaver, Cora M. Went, Joeson Wong, Dipti Jasrasaria, Eran Rabani | Summary: Since dissipative processes are ubiquitous in semiconductors, characterizing how electronic and thermal energy transduce and transport at the nanoscale is vital for understanding and leveraging their fundamental properties. For example, in low-dimensional […]

Kavli Affiliate: Debanjan Chowdhury | First 5 Authors: Thomas G. Kiely, Debanjan Chowdhury, , , | Summary: Electrons can organize themselves into charge-ordered states to minimize the effects of long-ranged Coulomb interactions. In the presence of a lattice, commensurability constraints lead to the emergence of incompressible Wigner-Mott insulators at various rational electron fillings, $nu~=p/q$. The […]
Kavli Affiliate: Zhiting Tian | First 5 Authors: Abhijit Biswas, Gustavo A. Alvarez, Tao Li, Joyce Christiansen-Salameh, Eugene Jeong | Summary: Heterostructures based on ultrawide-bandgap (UWBG) semiconductors (bandgap >4.0 eV), boron nitride (BN) and diamond are important for next-generation high-power electronics. However, in-situ hetero-epitaxy of BN/diamond or vice-versa remains extremely challenging, due to their non-trivial […]

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: María Camarasa-Gómez, Ashwin Ramasubramaniam, Jeffrey B. Neaton, Leeor Kronik, | Summary: The accurate description of electronic properties and optical absorption spectra is a long-standing challenge for density functional theory. Recently, the introduction of screened range-separated hybrid (SRSH) functionals for solid-state materials has allowed for the calculation […]
Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Chuan-Fu Yang | Summary: In this work, we consider Dirac-type operators with a constant delay less than two-fifths of the interval and not less than one-third of the interval. For our considered Dirac-type operators, an incomplete inverse spectral problem is studied. Specifically, when two complex […]
Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Chuan-Fu Yang | Summary: In this work, we consider Dirac-type operators with a constant delay less than half of the interval and not less than two fifths of the interval. For our considered Dirac-type operators, an inverse spectral problem is studied. Specifically, reconstruction of two […]
Kavli Affiliate: Grace Xing | First 5 Authors: Len van Deurzen, Jashan Singhal, Jimy Encomendero, Naomi Pieczulewski, Celesta Chang | Summary: Using low-temperature cathodoluminescence spectroscopy, we study the properties of N- and Al-polar AlN layers grown by molecular beam epitaxy on bulk AlN{0001}. Compared to the bulk AlN substrate, layers of both polarities feature a […]
