TL;DR: In this paper, an air-stable solution-based chemical treatment by an organic superacid was proposed to improve the photoluminescence and minority carrier lifetime of MoS 2 monolayers by over two orders of magnitude.
Abstract: Two-dimensional (2D) transition-metal dichalcogenides have emerged as a promising material system for optoelectronic applications, but their primary figure-of-merit, the room-temperature photoluminescence quantum yield (QY) is extremely poor. The prototypical 2D material, MoS 2 is reported to have a maximum QY of 0.6% which indicates a considerable defect density. We report on an air-stable solution-based chemical treatment by an organic superacid which uniformly enhances the photoluminescence and minority carrier lifetime of MoS 2 monolayers by over two orders of magnitude. The treatment eliminates defect-mediated non-radiative recombination, thus resulting in a final QY of over 95% with a longest observed lifetime of 10.8±0.6 nanoseconds. Obtaining perfect optoelectronic monolayers opens the door for highly efficient light emitting diodes, lasers, and solar cells based on 2D materials.

TL;DR: In this article, the authors study the trading of individual investors using transaction data and identifying buyer- or seller-initiated trades and find that small trade order imbalance correlates well with order imbalance based on trades from retail brokers.
Abstract: We study the trading of individual investors using transaction data and identifying buyer- or seller-initiated trades. We document four results: (1) Small trade order imbalance correlates well with order imbalance based on trades from retail brokers. (2) Individual investors herd. (3) When measured annually, small trade order imbalance forecasts future returns; stocks heavily bought underperform stocks heavily sold by 4.4 percentage points the following year. (4) Over a weekly horizon, small trade order imbalance reliably predicts returns, but in the opposite direction; stocks heavily bought one week earn strong returns the subsequent week, while stocks heavily sold earn poor returns.

01 Jan 2010TL;DR: In this article, a simple formula for the valuation of uncertain income streams consistent with rational investor behavior and equilibrium in financial markets is developed for the pricing of an option as a function of its associated stock, even though investors can trade only at discrete points in time.
Abstract: A simple formula is developed for the valuation of uncertain income streams consistent with rational investor behavior and equilibrium in financial markets. Applying this formula to the pricing of an option as a function of its associated stock, the Black–Scholes formula is derived even though investors can trade only at discrete points in time.
