Proceedings ArticleDOI
Array-based vapor sensing using chemically sensitive, polymer composite resistors
Mark C. Lonergan,Michael S. Freund,Erik J. Severin,Brett J. Doleman,Robert H. Grubbs,Nathan S. Lewis +5 more
TL;DR: In this article, the authors describe the construction of simple, low-power, broadly responsive vapor sensors, with each element containing either carbon black or poly(pyrrole) as the conducting phase mixed with one of several different organic polymers as the insulating phase.
Journal ArticleDOI
Control of the pH-Dependence of the Band Edges of Si(111) Surfaces Using Mixed Methyl/Allyl Monolayers
Erik Johansson,Shannon W. Boettcher,Leslie E. O'Leary,Andrey D. Poletayev,Stephen Maldonado,Bruce S. Brunschwig,Nathan S. Lewis +6 more
TL;DR: The open-circuit potentials of p-Si/((MV^(2+)/MV+))(aq)) junctions with Si(111) surfaces functionalized with H−, CH_(3)-, CH-(2)CHCH_(2)−, or mixed CH-(3)-/CH(2)-terminated n-Si(111)-monolayers have been investigated as the solution pH was changed from 2.5 to 11.9 V as discussed by the authors.
Journal ArticleDOI
Detection of organic vapors and NH3(g) using thin-film carbon black–metallophthalocyanine composite chemiresistors
TL;DR: In this paper, thin-film chemiresistive vapor sensors have been fabricated using composites of carbon black (CB) and metallophthalocyanines, which exhibited large, rapid, and reversible relative differential resistance changes upon exposure to a series of test organic vapors.
Journal ArticleDOI
Measurement of interfacial charge-transfer rate constants at n-type InP/CH3OH junctions
TL;DR: In this paper, the steady-state current density vs potential methods have been used to measure interfacial electron-transfer rate constants at n-type indium phosphide/liquid junctions.
Proceedings ArticleDOI
Radial PN junction, wire array solar cells
Brendan M. Kayes,Michael A. Filler,Michael David Henry,James R. Maiolo,Michael D. Kelzenberg,Morgan C. Putnam,Joshua M. Spurgeon,Katherine E. Plass,Axel Scherer,Nathan S. Lewis,Harry A. Atwater +10 more
TL;DR: In this article, the potential of low-cost catalysts such as Cu and Ni to fabricate Si wire arrays with potentially higher minority-carrier lifetimes than is possible with a Au catalyst is discussed.
