Defect states in monolayer hexagonal BN: A comparative DFT and DFT-1/2 study
(Elsevier, 2020)Hexagonal boron nitride (h-BN) acts like a semiconductor vacuum to point defects enabling stable and controllable spin states at room temperature which qualifies them for quantum technological applications. To characterize ... -
Dropping of electromagnetic waves through localized modes in three-dimensional photonic band gap structure
(AIP Publishing, 2002-12-03)We experimentally demonstrate trapping and dropping of photons through localized cavity modes in three-dimensional layer-by-layer photonic crystal structures. By creating acceptor- and donor-like cavities which are coupled ... -
Electronic structure and optical properties of monolayer semiconductors: a computational study
(Bilkent University, 2021-09)Interest on monolayer semiconductors is rapidly growing in recent years. One of the prominent members is hexagonal boron nitride (h-BN). At room tem-perature, it harbors an environment similar to semiconductor vacuum for ... -
Physics and applications of coupled-cavity structures in photonic crystals
(Bilkent University, 2002)We proposed and demonstrated a new type of propagation mechanism for the electromagnetic waves in photonic band gap materials. Photons propagate through coupled cavities due to interaction between the highly localized ... -
Physics and applications of photonic crystals
(Bilkent University, 2000)We first fabricated a dielectric based layer-by-layer photonic crystal, with a three-dimensional photonic band gap at microwave frequencies. We investigated the transmission, reflection and defect characteristics of the ... -
Sözleşme dışı sorumluluk hukukunda otonom sistemler
(Bilkent University, 2022-05)Yapay zekâ ve robotik bilimindeki gelişmeler otonom sistemlerin yaygınlaşmasını sağlamış; bu tür uygulamalar artık yalnızca bilimsel ya da endüstriyel aktivitelerin alanında olmaktan çıkıp bireylerin günlük hayatlarında ...
