1.
Wanger D, Correa R, Dauler E, Bawendi M
Nano Lett . 2013 Nov; 13(12):5907-12. PMID: 24256125
We present a quantitative measurement of the number of trapped carriers combined with a measurement of exciton quenching to assess limiting mechanisms for current losses in PbS-quantum-dot-based photovoltaic devices. We...

Cui J, Beyler A, Marshall L, Chen O, Harris D, Wanger D, et al.
Nat Chem . 2013 Jun; 5(7):602-6. PMID: 23787751
The spectral linewidth of an ensemble of fluorescent emitters is dictated by the combination of single-emitter linewidths and sample inhomogeneity. For semiconductor nanocrystals, efforts to tune ensemble linewidths for optical...

Manfrinato V, Wanger D, Strasfeld D, Han H, Marsili F, Arrieta J, et al.
Nanotechnology . 2013 Mar; 24(12):125302. PMID: 23466608
We demonstrated a technique to control the placement of 6 nm-diameter CdSe and 5 nm-diameter CdSe/CdZnS colloidal quantum dots (QDs) through electron-beam lithography. This QD-placement technique resulted in an average...

Mentzel T, Wanger D, Ray N, Walker B, Strasfeld D, Bawendi M, et al.
Nano Lett . 2012 Jul; 12(8):4404-8. PMID: 22784104
We present the first semiconductor nanocrystal films of nanoscale dimensions that are electrically conductive and crack-free. These films make it possible to study the electrical properties intrinsic to the nanocrystals...

Osedach T, Zhao N, Andrew T, Brown P, Wanger D, Strasfeld D, et al.
ACS Nano . 2012 Apr; 6(4):3121-7. PMID: 22480161
We investigate the bias-stress effect in field-effect transistors (FETs) consisting of 1,2-ethanedithiol-treated PbS quantum dot (QD) films as charge transport layers in a top-gated configuration. The FETs exhibit ambipolar operation...

Strasfeld D, Dorn A, Wanger D, Bawendi M
Nano Lett . 2012 Jan; 12(2):569-75. PMID: 22250976
We fabricated planar PbS quantum dot devices with ohmic and Schottky type electrodes and characterized them using scanning photocurrent and photovoltage microscopies. The microscopy techniques used in this investigation allow...

Brown P, Lunt R, Zhao N, Osedach T, Wanger D, Chang L, et al.
Nano Lett . 2011 Jun; 11(7):2955-61. PMID: 21661734
The ability to engineer interfacial energy offsets in photovoltaic devices is one of the keys to their optimization. Here, we demonstrate that improvements in power conversion efficiency may be attained...

J Am Chem Soc . 2008 Dec; 130(51):17290-2. PMID: 19053441
The fullerene adducts 1a and 1b, whose molecular shapes either promote or hinder the formation of 1-D stacks, have been examined for their potential to form 1-D wire-like domains in...
