TL;DR: An overview of the key aspects of graphene and related materials, ranging from fundamental research challenges to a variety of applications in a large number of sectors, highlighting the steps necessary to take GRMs from a state of raw potential to a point where they might revolutionize multiple industries are provided.
Journal ArticleDOI
Hybrid graphene-quantum dot phototransistors with ultrahigh gain
Gerasimos Konstantatos,Michela Badioli,Louis Gaudreau,Johann Osmond,Maria Bernechea,F. Pelayo García de Arquer,Fabio Gatti,Frank H. L. Koppens +7 more
TL;DR: A gain of ∼10(8) electrons per photon and a responsivity of ∼ 10(7) A W(-1) in a hybrid photodetector that consists of monolayer or bilayer graphene covered with a thin film of colloidal quantum dots is demonstrated.
Journal ArticleDOI
Solution-processed PbS quantum dot infrared photodetectors and photovoltaics
Steve Mcdonald,Gerasimos Konstantatos,Shiguo Zhang,Paul W. Cyr,Ethan J. D. Klem,Larissa Levina,Edward H. Sargent +6 more
TL;DR: Sittingizing conjugated polymers with infrared-active nanocrystal quantum dots provides a spectrally tunable means of accessing the infrared while maintaining the advantageous properties of polymers, and makes use of the wavelength tunability afforded by the nanocrystals to show photocurrent spectra tailored to three different regions of the infrared spectrum.
Journal ArticleDOI
Ultrasensitive solution-cast quantum dot photodetectors
Gerasimos Konstantatos,Ian A. Howard,Armin Fischer,Sjoerd Hoogland,Jason Paul Clifford,Ethan J. D. Klem,Larissa Levina,Edward H. Sargent +7 more
TL;DR: The tailored selection of absorption onset energy through the quantum size effect, combined with deliberate engineering of the sequence of nanoparticle fusing and surface trap functionalization, underlie the superior performance achieved in this readily fabricated family of devices.

Hybrid graphene-quantum dot phototransistors with ultrahigh gain
Gerasimos Konstantatos,Michela Badioli,Louis Gaudreau,Johann Osmond,Maria Bernechea,F. Pelayo García de Arquer,Fabio Gatti,Frank H. L. Koppens +7 more
TL;DR: In this article, the authors exploit the strong light absorption in quantum dots and the two-dimensionality and high mobility of graphene to merge these materials into a hybrid system for photodetection with extremely high sensitivity.
