Carbon nanotube substrates enhance SARS-CoV-2 spike protein ion yields in matrix assisted laser desorption-ionization mass spectrometry

T. Schenkel, A. M. Snijders, K. Nakamura +15

Nanostructured surfaces enhance ion yields in matrix assisted laser desorption-ionization mass spectrometry (MALDI-MS). The spike protein complex, S1, is one fingerprint signature…

Platform-agnostic waveguide integration of high-speed photodetectors with evaporated tellurium thin films

Geun Ho Ahn, Alexander D. White, Hyungjin Kim +8

Many attractive photonics platforms still lack integrated photodetectors due to inherent material incompatibilities and lack of process scalability, preventing their widespread dep…

Inhibited nonradiative decay at all exciton densities in monolayer semiconductors

Hyungjin Kim, Shiekh Zia Uddin, Naoki Higashitarumizu +2

Most optoelectronic devices operate at high photocarrier densities, where all semiconductors suffer from enhanced nonradiative recombination. Nonradiative processes proportionately…

Electrical suppression of all nonradiative recombination pathways in monolayer semiconductors

Der-Hsien Lien, Shiekh Zia Uddin, Matthew Yeh +5

Defects in conventional semiconductors substantially lower the photoluminescence (PL) quantum yield (QY), a key metric of optoelectronic performance that directly dictates the maxi…

Suppressing Diffusion-Mediated Exciton Annihilation in 2D Semiconductors Using the Dielectric Environment

Aaron J. Goodman, Der-Hsien Lien, Geun Ho Ahn +5

Atomically thin semiconductors such as monolayer MoS2 and WS2 exhibit nonlinear exciton-exciton annihilation at notably low excitation densities (below ~10 excitons/um2 in MoS2). H…
