Study of two‐dimensional materials by Ultrafast laser spectroscopy (CAT#: STEM-ST-0329-WXH)

Introduction

Ultrathin two-dimensional (2D) nanomaterials are a new class of nanomaterials with sheet-like structures and transverse dimensions larger than 100 nm, while the thickness is typically less than 5 nm. Due to their unique shapes, 2D nanomaterials possess large surface and anisotropic physical/chemical properties.




Principle

Ultrafast laser spectroscopy involves studying ultrafast events that take place in a medium using ultrashort pulses and delays for time resolution. It usually involves exciting the medium with one (or more) ultrashort laser pulse(s) and probing it a variable delay later with another.

Applications

study photoinduced dynamical processes in atoms, molecules, nanostructures, and solids
