Biography
Igor Pavlovich Marko was born in 1974 in Belarus. He graduated with distinction from the department of quantum radiophysics and optoelectronics of the Belarusian State University in 1996. From 1996 until 2001 he studied the optical properties of ZnSe- and GaN-based wide bandgap semiconductors and optically pumped lasers in the Laboratory of Semiconductor Optics of B. I. Stepanov Institute of Physics of the Belarusian Academy of Sciences. He received the degree of PhD in 2000 (thesis: "Optically Pumped Lasers Based on ZnSe Epitaxial Layers and ZnMgSSe/ZnSe Quantum Well Heterostructures"). Since 2001 have been studying the properties of near-IR and mid-IR III-V based interband quantum dots, quantum well lasers, short-wavelength (<3.5um) quantum cascade lasers, InGaNAs avalanche photodiodes at the University of Surrey. Most recent activity includes developing of a new III-V material systems containing Bi.
Research Interests
My current research interests includes III-V visible light-emitting diodes and lasers, near-infrared quantum dot and quantum well lasers for telecommunications, avalanche photo-diodes for 1.3-1.5μm spectral range, mid-infrared interband and quantum cascade lasers. Most recent projects include developing of a new III-V material systems containing Bi (GaAsBi/GaAs, InGaAsBi/InP).
