Dynamic lattice distortions driven by surface trapping in semiconductor nanocrystals

Kavli Affiliate: Paul Alivisatos | First 5 Authors: Burak Guzelturk, Benjamin L. Cotts, Dipti Jasrasaria, John P. Philbin, David A. Hanifi | Summary: Nonradiative processes limit optoelectronic functionality of nanocrystals and curb their device performance. Nevertheless, the dynamic structural origins of nonradiative relaxations in nanocrystals are not understood. Here, femtosecond electron diffraction measurements corroborated by […]

QubiC: An open source FPGA-based control and measurement system for superconducting quantum information processors

Kavli Affiliate: Irfan Siddiqi | First 5 Authors: Yilun Xu, Gang Huang, Jan Balewski, Ravi Naik, Alexis Morvan | Summary: As quantum information processors grow in quantum bit (qubit) count and functionality, the control and measurement system becomes a limiting factor to large scale extensibility. To tackle this challenge and keep pace with rapidly evolving […]

The role of disorder in the synthesis of metastable ternary nitrides

Kavli Affiliate: Kristin A. Persson | First 5 Authors: Rachel Woods-Robinson, Vladan Stevanović, Stephan Lany, Karen N. Heinselman, Kristin A. Persson | Summary: In materials science, it is often assumed that ground state crystal structures predicted by density functional theory are the easiest polymorphs to synthesize. Ternary nitride materials, with many possible metastable polymorphs, provide […]

Tunable ferromagnetism at non-integer filling of a moiré superlattice

Kavli Affiliate: Michael F. Crommie | First 5 Authors: Guorui Chen, Aaron L. Sharpe, Eli J. Fox, Shaoxin Wang, Bosai Lyu | Summary: The flat bands resulting from moir’e superlattices in magic-angle twisted bilayer graphene (MATBG) and ABC-trilayer graphene aligned with hexagonal boron nitride (ABC-TLG/hBN) have been shown to give rise to fascinating correlated electron […]

Ultra-Narrow TaS2 Nanoribbons

Kavli Affiliate: Alex Zettl | First 5 Authors: Jeffrey D. Cain, Sehoon Oh, Amin Azizi, Scott Stonemeyer, Mehmet Dogan | Summary: Imposing additional confinement in two-dimensional (2D) materials can yield further control over the associated electronic, optical, and topological properties. However, synthesis of ultra-narrow nanoribbons (NRs) remains a challenge, particularly for the transition metal dichalcogenides […]

Band gaps of crystalline solids from Wannier-localization based optimal tuning of a screened range-separated hybrid functional

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Dahvyd Wing, Guy Ohad, Jonah B. Haber, Marina R. Filip, Stephen E. Gant | Summary: Accurate prediction of fundamental band gaps of crystalline solid state systems entirely within density functional theory is a long standing challenge. Here, we present a simple and inexpensive method that achieves […]

Non-Covalent Dimerization after Enediyne Cyclization on Au(111)

Kavli Affiliate: Michael F. Crommie | First 5 Authors: Dimas G. de Oteyza, Alejandro Pérez Paz, Yen-Chia Chen, Zahra Pedramrazi, Alexander Riss | Summary: We investigate the thermally-induced cyclization of 1,2 – bis(2 – phenylethynyl)benzene on Au(111) using scanning tunneling microscopy and computer simulations. Cyclization of sterically hindered enediynes is known to proceed via two […]
