Ball,Bernard Wenger,Bernd Stannowski,Henry J. Snaith +26 more
TL;DR: High-resilience positive-intrinsic-negative perovskite solar cells are demonstrated by incorporating a piperidinium-based ionic compound into the formamid inium-cesium lead-trihalide perovSKite absorber, and detailed degradation routes that contribute to the failure of aged cells are revealed.
Journal ArticleDOI
Photothermoelectric Effect in Suspended Semiconducting Carbon Nanotubes
TL;DR: Measurements show that photothermoelectric phenomena play a critical role in the optoelectronic properties of suspended CNT FETs and identified regimes where they overwhelm the photovoltaic mechanism.
Journal ArticleDOI
Light soaking in metal halide perovskites studied via steady-state microwave conductivity
C. Lowell Watts,Lee Aspitarte,Yen-Hung Lin,Wen Li,Wen Li,Radwan Elzein,Rafik Addou,Min Ji Hong,Gregory S. Herman,Henry J. Snaith,John G. Labram +10 more
TL;DR: In this article, the light-soaking effect in metal halide perovskites was investigated using steady-state microwave conductivity, a contactless probe of electronic properties of semiconductors.
Journal ArticleDOI
Determining the Chiral Index of Semiconducting Carbon Nanotubes Using Photoconductivity Resonances
TL;DR: In this article, the authors used photoconductivity spectroscopy to identify the unique chiral structure of individual carbon nanotubes (CNTs) by measuring photo-conductivity peaks associated with individual CNTs.
Journal ArticleDOI
Giant modulation of the electronic band gap of carbon nanotubes by dielectric screening
Lee Aspitarte,Daniel R. McCulley,Andrea Bertoni,Joshua O. Island,Marvin Ostermann,Massimo Rontani,Gary A. Steele,Ethan D. Minot +7 more
TL;DR: In this article, the authors use dielectric liquids to screen electron-electron (e-e) interactions in individual suspended ultra-clean carbon nanotubes (CNTs).
