Structural Hole Traps in III-V Quantum Dots
Ezra Alexander, Alexandra Alexiu, Matthias Kick +1
Non-toxic III-V quantum dots (QDs) are plagued with a higher density of performance-limiting trap states than II-VI and IV-VI QDs. Such trap states are generally understood to aris…

Understanding Trap States in InP and GaP Quantum Dots Through Density Functional Theory
Ezra Alexander, Matthias Kick, Alexandra McIsaac +1
The widespread application of III-V colloidal quantum dots (QDs) as non-toxic, highly tunable emitters is stymied by their high density of trap states. Here, we utilize density fun…

Broad Yet Narrow: Super-resolution techniques to simulate electronic spectra of large molecular systems
Matthias Kick, Ezra Alexander, Anton Beiersdorfer +1
An accurate treatment of electronic spectra in large systems with a technique such as time dependent density functional theory (TDDFT) is computationally challenging. Due to the Ny…
