    • Control of LED emission with functional dielectric metasurfaces 

      Khaidarov, E.; Liu, Z.; Paniagua-Domínguez, R.; Ha, S. T.; Valuckas, V.; Liang, X.; Akimov, Y.; Bai, P.; Png, C. E.; Demir, Hilmi Volkan; Kuznetsov, A. I. (Wiley, 2020)
      The improvement of light‐emitting diodes (LEDs) is one of the major goals of optoelectronics and photonics research. LED integration to complex photonic devices requires precise control of the wavefront of the emitted ...
    • Lasing action in single subwavelength particles supporting supercavity modes 

      Mylnikov, V.; Ha, S. T.; Pan, Z.; Valuckas, V.; Paniagua-Domínguez, R.; Demir, Hilmi Volkan; Kuznetsov, A. I. (American Chemical Society, 2020-05)
      On-chip light sources are critical for the realization of fully integrated photonic circuitry. So far, semiconductor miniaturized lasers have been mainly limited to sizes on the order of a few microns. Further reduction ...
    • Room-temperature lasing in colloidal nanoplatelets via mie-resonant bound states in the continuum 

      Wu, M.; Ha, S. T.; Shendre, S.; Durmuşoğlu, E. G.; Koh, W.-K.; Abujetas, D. R.; Sanchez-Gil, J. A.; Paniagua-Domínguez, R.; Demir, Hilmi Volkan; Kuznetsov, A. I. (American Chemical Society, 2020)
      Solid-state room-temperature lasing with tunability in a wide range of wavelengths is desirable for many applications. To achieve this, besides an efficient gain material with a tunable emission wavelength, a high ...
    • Ultrahigh-efficiency aqueous flat nanocrystals of CdSe/CdS@Cd1−xZnxS colloidal core/crown@alloyed-shell quantum wells 

      Shendre, S.; Delikanlı, Savaş; Li, M.; Dede, Didem; Pan, Z.; Ha, S. T.; Fu, Y. H.; Hernández-Martínez, Pedro L.; Yu, J.; Erdem, Onur; Kuznetsov, A. I.; Dang, C.; Sum, T. C.; Demir, Hilmi Volkan (Royal Society of Chemistry, 2019)
      Colloidal semiconductor nanoplatelets (NPLs) are highly promising luminescent materials owing to their exceptionally narrow emission spectra. While high-efficiency NPLs in non-polar organic media can be obtained readily, ...
