Journal Article
Hong, B. H., Rybchenko, S. I., Itskevich, I. E., Haywood, S. K., Tan, C. H., Vines, P., & Hugues, M. (2012). Modeling and analysis of intraband absorption in quantum-dot-in-well mid-infrared photodetectors. Journal of applied physics, 111(3), 033713. https://doi.org/10.1063/1.3684603

Intraband absorption in quantum-dot-in-a-well (DWELL) mid-infrared photodetectors is investigated using photocurrent spectroscopy and computationally cost-effective modeling linked to experimental data. The DWELL systems are challenging for modeling... Read More about Modeling and analysis of intraband absorption in quantum-dot-in-well mid-infrared photodetectors.

Applicability of the kp method to modeling of InAs/GaSb short-period superlattices (2009)
Journal Article
Hong, B. H., Rybchenko, S. I., Itskevich, I. E., Haywood, S. K., Intartaglia, R., Tasco, V., Rainò, G., & De Giorgi, M. (2009). Applicability of the kp method to modeling of InAs/GaSb short-period superlattices.

We investigate the long-standing controversy surrounding modeling of the electronic spectra of InAs/GaSb short-period superlattices (SPSLs). Most commonly, such modeling for semiconductor heterostructures is based on the kp method. However, this meth...
