Rate My Professor Kevin Stokes

Stokes' investigations delve into quantum confinement effects, where the physical confinement of electrons, excitons, and phonons within nanoparticles modifies optical, magnetic, and electronic properties. Surface effects play a crucial role, as a significant portion of atoms resides on nanoparticle surfaces, rendering properties highly sensitive to surface chemistry. His studies on composite materials examine interfaces that form energy barriers for charge carriers and phonons, leveraging quantum confinement and selective energy scattering to customize material properties. Key research areas include thermoelectric materials, nanocomposites, nanostructuring for enhanced thermoelectric performance, half-Heusler alloys, bismuth telluride, nanoparticle inclusions, charge transport, and thermal conductivity reduction. Notable publications encompass 'Correlation between microstructure and drastically reduced lattice thermal conductivity in bismuth telluride/bismuth nanocomposites for high thermoelectric figure of merit' (2015), 'Distribution of impurity states and charge transport in Zr0.25Hf0.75Ni1+xSn1-ySby nanocomposites' (2015), 'Effect of NiTe Nanoinclusions on Thermoelectric Properties of Bi2Te3' (2012), 'Simultaneous Large Enhancements in Thermopower and Electrical Conductivity of Bulk Nanostructured Half-Heusler Alloys' (2011), and 'Enhancement in Thermoelectric Figure of Merit in Nanostructured Bi2Te3 with Semimetal Nanoinclusions' (2011). His scholarly output has accumulated over 1,900 citations.
