Philippe Gillet, Andras Kis, Oleg Yazyev, Oriol López Sánchez, Alessandro Surrente, Dmitry Ovchinnikov, Michele Pizzochero, Ming-Wei Chen
Transition metal dichalcogenides (TMDCs), together with other two-dimensional (2D) materials, have attracted great interest due to the unique optical and electrical properties of atomically thin layers. In order to fulfill their potential, developing large ...
American Chemical Society2017Manufacturing with light - micro-assembly of opto-electronic microstructures
Optical micromanipulation allows the movement and patterning of discrete micro-particles within a liquid environment. However, for manufacturing applications it is desirable to remove the liquid, leaving the patterned particles in place. In this work, we h ...
Optical Soc Amer2017Thermodynamics of the Segregation of a Kinetically Trapped Two-Dimensional Amorphous Metal-Organic Network
Surface-confined self-assembled molecular networks are commonly described as crystalline structures with short- and long-range order. Few exceptions to this trend are found in the literature reporting on amorphous and glassy networks and, discussing the or ...
