Physics Prof, Collaborators Pioneer Advances in Carbyne Research

Professor Richard Hartmann of the De La Salle University Department of Physics co-authored an article titled, “Polarization-sensitive photoluminescence from aligned carbon chains terminated by gold clusters”, which has been accepted for publication in Physical Review Letters (PRL). 

The article is the first from DLSU to be published in PRL, which is the world’s premier physics letter journal and the American Physical Society’s flagship publication. Since 1958 it has contributed to APS’s mission to advance and diffuse the knowledge of physics by publishing seminal research by Nobel Prize–winning and other distinguished researchers in all fields of physics.

The study focuses on carbyne, a chain of carbon atoms that is ultimately a thin one-dimensional material. In the paper, the researchers demonstrate that by adding gold to the end of carbyne chains, one can grow thin films of highly aligned chains. 

It experimentally shows and theoretically explains the optical response of the material, demonstrating it as the ultimate thin polarizer. Gold-terminated carbon chain arrays are promising candidates for nanoscale logic elements in emerging light-controlled quantum devices. This paves the way for a new class of ultimately thin, polarization-sensitive emitters to be used in future integrated quantum photonics devices.

The latest impact factor of Physical Review Letters is 9.185 and it is ranked by Scopus in the 94th percentile of the world’s Physics journals.
