Description:: Light provides a high-speed and coherent medium for controlling quantum states. In semiconductors, coherent optical effects have been used extensively to lift spin degeneracy on ultrafast timescales and demonstrate high-fidelity control of quantum spin states. Extending this approach to novel pseudospins in monolayer transition metal dichalcogenides (TMDs), in this thesis...

Description:: Characterizing the interaction of light and matter has become increasingly important in recent decades, as devices scale down, data transfer speeds up, and the use of photon-based technology (photonics and optoelectronics) becomes widespread. Copper chloride (CuCl) thin films and zinc oxide (ZnO) inverse opal photonic crystals are the two material...
