Mechanical Properties and Phase Stability of Monoborides using Density Functional Theory CalculationsHyojung Kim & Dallas R. Trinkle
This data demonstrates the Ti-monoborides with improved polycrystalline elastic properties such as Young's modulus and Pugh's ratio, and stacking fault energies. The lattice parameters, total energies and elastic constants of monoborides are computed using density functional theory
Relaxed structures and pseudopotentials.
Data corresponds to the demonstration of photonic annealing to cure inkjet-printed graphene patterns. Few-layer graphene flakes are produced by liquid-phase exfoliation and stabilized by ethyl cellulose to formulate inks suitable for inkjet printing. Photonic annealing is applied as an alternative to thermal annealing for rapid processing and integration on temperature-sensitive substrates. Characterization of the materials using atomic force microscopy, Raman spectroscopy, thermal gravimetric analysis, and electrical measurements reveals suitable properties for application in printed and...

This work contains a series of SEM images and descriptions describing various etches used commonly for dielectrics (SiNx, SiO2) and Si. Some are failures, some are successes. Each was taken on the S4800 Hitachi SEM in the Micro and Nano Technology Lab at the University of Illinois at Urbana-Champaign during the RET taking place the summer of 2016.
Ultrafast Exciton Dissociation and Long-Lived Charge Separation in a Photovoltaic Pentacene−MoS2 van der Waals HeterojunctionStephanie B. Homan, Vinod K. Sangwan, Itamar Balla, Hadallia Bergeron, Emily A. Weiss & Mark C. Hersam
This data corresponds to the study of the dynamics of charge transfer in an ultrathin p-n heterojunction of the organic molecule of pentacene and monolayer MoS2. The transient absorption spectroscopy measurements show that exciton dissociation occurs on an ultrafast timescale and that the charge separation is long-lived with respect to recombination and trapping mechanisms.

Mutual Photoluminescence Quenching and Photovoltaic Effect in Large-Area Single-Layer MoS2–Polymer HeterojunctionsTejas A. Shastry, Itamar Balla, Hadallia Bergeron, Samuel H. Amsterdam, Tobin J. Marks & Mark C. Hersam
This data corresponds to the demonstration of the photovoltaic effect in an ultrathin heterojunction of monolayer MoS2 and poly[[4,8-bis[(2- ethylhexyl)oxy]benzo[1,2-b:4,5-b′]dithiophene-2,6-diyl][3-flu-oro-2[(2-ethylhexyl)carbonyl]thieno[3,4-b]thiophenediyl]] (PTB7). Tuning of the PTB7 thickness enables complete quenching of the MoS2 photoluminescence. Solar cells made from the heterojunction on transparent indium tin oxide demonstrate exceptional current density per absorbing thickness. DOI: 10.1021/acsnano.6b06592
This data was collected to study the growth and relaxation dynamics of an icosahedral quasicrystal from a liquid. The composition of the imaged QC is Al-19at%Pd-10at%Mn, and the growth and relaxation dynamics of an icosahedral quasicrystal were observed under slow cooling conditions. The quasicrystalline phase shows weaker projection intensity because of more X-ray absorption resulting from its heavy elemental (Pd and Mn) composition. This contrast difference allowed us to segment the quasicrystal from the liquid...
Real-space Observation of Magnetic Excitations and Avalanche Behavior in Artificial Quasicrystal LatticesV. Brajuskovic, F. Barrows, C.D. Phatak & A.K. Petford-Long
Thin films of Permalloy were patterned into quasicrystal artificial spin ice lattices. Lorentz TEM was used to image the magnetic induction in the lattices in the as-deposited state, after a demagnetization protocol, and after thermal annealing in a sputter deposition chamber.
