Description:: Van der Waals, or layered, materials offer a flexible platform to tune properties via exfoliation down to the single- or few-layer limit; they are at the forefront of cutting-edge materials science and engineering research because of the innumerable ways to tune materials as a function of thickness or composition. Due...

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:: The limits of miniaturization of electronic device components and the steady need for faster computation power have motivated the discovery and cultivation of low-dimensional materials. Among these, two-dimensional (2D) materials have exhibited a wide range of superlative optoelectronic, thermal and mechanical properties. The interest in 2D materials took-off with the...
