Reflection of polar molecules


Research objectives and content
The applicant intends to study the reflection of polar molecules to show the possibility of manipulating a molecular beam. The project is a direct application of recent results on oriented molecules obtained both by the laboratory of Steven Stolte and that of the applicant. The goal of the project is to develop suitable techniques so as to conserve the projection quantum | number M of the total rotational momentum J of the incoming molecule along its scattering path. This technique appears to be a critical issue in order to extend the reslts of atomic manipulation (such as Doppler cooling) to the rich molecular domain. In the planned experiments, the reflection will be produced by a specially designed electric field shaped by | microstructures. The desired interrogation f the M quantum number distribution upon the reflection will be obtained by | Laser Induced Fluorescence. This pilot study is an important step toward molecular trapping and nanoscale lithography.
Training content (objective, benefit and expected impact)
The applicant will broaden his scientific skills by learning the state-of-the-art technology on polarisation and orientation- conserving techniques, the speciality of the laser laboratory of the Steven Stolte group . The acquisition of this technique will be extremely useful when applying to a position in the field of nanoscale technology. Links with industry / industrial relevance (22)
A direct application of such research is the focusing of molecules with (laser) fields. It should permit to control the orientation of molecules deposed in nanostructure, which has important applications in nanoscale lithography and electronics (Philips, Motorola, etc .)
