Identifying Contact Barrier Types in Few-Layer MoS2 Devices Using Correlative IV, LBIC, and Bias-Dependent KPFM
Ariane Ufer, Zeinab Eftekhari, Benjamin Mayer +4
Electrical contacts between metals and two-dimensional (2D) semiconductors such as molybdenum disulfide (MoS2) critically govern device performance, yet their microscopic nature re…
Enhanced Absorption in thin and ultrathin silicon films by 3D photonic band gap back reflectors
Devashish Sharma, Shakeeb B. Hasan, Rebecca Saive +2
Since thin-film silicon solar cells have limited optical absorption, we explore the effect of a nanostructured back reflector to recycle the unabsorbed light. As a back reflector w…
Three-dimensional nanoimprint lithography using two-photon lithography master samples
Rebecca Saive, Colton R. Bukowsky, Harry A. Atwater
We demonstrate three-dimensional (3-D) nanoimprint lithography using master samples initially structured by two-photon lithography. Complex geometries like micro prisms, micro para…
Total Internal Reflection for Effectively Transparent Solar Cell Contacts
Phillip Jahelka, Rebecca Saive, Harry Atwater
A new strategy for eliminating photocurrent losses due to the metal contacts on the front of a solar cell was proposed, simulated, and tested. By placing triangular cross-section l…
Broadband Purcell enhanced emission dynamics of quantum dots in linear photonic crystal waveguides
Arne Laucht, Thomas Günthner, Simon Pütz +8
The authors investigate the spontaneous emission dynamics of self-assembled InGaAs quantum dots embedded in GaAs photonic crystal waveguides. For an ensemble of dots coupled to gui…
