NRL, AFRL Develop Direct-Write Quantum Calligraphy in Monolayer Semiconductors

By Daniel Parry, U.S. Naval Research Laboratory Public Affairs February 13, 2019

Scientists at the U.S. Naval Research Laboratory (NRL) and the Air Force Research Laboratory (AFRL) have developed a way to directly write quantum light sources, which emit a single photon of light at a time, into monolayer semiconductors such as tungsten diselenide (WSe₂). Single photon emitters (SPEs), or quantum emitters, are key components in a wide range of nascent quantum-based technologies, including computing, secure communications, sensing and metrology. More

1776’s host walks center-stage before the Innovation Discovery Event, where four NRL researchers presented to a panel of private and public, research and development professionals on Nov. 28, 2018. As the nation’s largest network of entrepreneurial incubators, 1776 offers access to a global network of connections with established institutions and corporations, influencers, expert mentors, and investors. Here, the U.S. Naval Research Laboratory is able to work in collaborative spaces where researchers can be

NRL Research Paves Way Toward Development of New Monolayer Materials

By Daniel Parry November 14, 2018

Scientists at the U.S. Naval Research Laboratory (NRL) have discovered the reason for the large variations observed in the optical properties of new single monolayer semiconductors such as tungsten disulphide (WS₂). Single monolayer transition metal dichalcogenides (TMDs), such as WS₂, are an emerging class of materials that exhibit many promising optoelectronic properties, with the potential for future device applications. More

An emerging class of semiconductor heterostructures involves stacking discrete monolayers such as transition metal dichalcogenides (TMDs), e.g. molybdenum diselenide (MoSe<sub>2</sub>) and tungsten diselenide (WSe<sub>2</sub>), to form van der Waals heterostructures. Both emission features originate from excitonic transitions that are indirect in momentum space and are split by spin−orbit coupling. (U.S. Naval Research Laboratory)
