Raman spectroscopy is the workhorse for label-free analysis of molecules. It relies on the inelastic scattering of incoming monochromatic light impinging molecules of interest. This effect leads to a very weak emission of light spectrum that provides a sig ...

3D monolithic dielectrophoretic actuators and resonators written by femtosecond laser

Tao Yang

The last few decades have witnessed exciting advances in micro-opto-electro-mechanical systems (MOEMS) including revolutionary development of fabrication processes and an ever increasing expansion of their domain of applications. In parallel, femtosecond l ...

State-to-state scattering of CH₄ from Ni(111) and Gr/Ni(111)

Maarten Eduard van Reijzen

In this thesis, I describe the design and implementation of the first state-to-state surface scattering experiments for methane from clean single crystalline surfaces in ultrahigh vacuum. The experiments use infrared laser pumping to prepare the incident C ...

High-energy femtosecond hydrogen Raman laser

Christoph Peter Hauri, Mostafa Shalaby

High-energy pulses at 1.28 mu m are demonstrated by stimulated Raman scattering using two chirped pulses of a Ti:Sapphire laser in hydrogen. The Stokes pulse carrying record-high energy of 4.4 mJ is recompressed to 80 fs. ...

The dynamics of excited electrons and holes in single layer (SL) MoS2 have so far been difficult to disentangle from the excitons that dominate the optical response of this material. Here, we use time- and angle-resolved photoemission spectroscopy for a SL ...

Amer Chemical Soc2015

Various domains present the challenges of responding to stimuli in a specific manner, with the desired sensitivity or functionality, and only when required. Stimuli-responsive systems that are appropriately designed can effectively meet these challenges. H ...
