DESCRIPTION:Speakers: Dongchen Qi (Department of Chemistry and Physics\, L
 IMS\, La Trobe University)\nOrganic semiconductors have important applicat
 ions in organic electronics and other novel hybrid devices. In these devic
 es\, the transport of charge carriers across the interfaces between organi
 c molecules and electrodes plays an important role in determining the devi
 ce performance. Charge transfer dynamics at these interfaces usually occur
 s at the several femtoseconds timescale which presents tremendous challeng
 es to conventional pumb-probe based time-resolved techniques. In this talk
 \, I will introduce our recent work in the application of synchrotron-base
 d core-hole clock (CHC) spectroscopy on the quantitative characterisation 
 of charge transfer dynamics in several model organic/electrode systems. Th
 e CHC technique allows us to quantify the interfacial charge transfer time
 s with element and site/orbital specificity. Combined with other soft x-ra
 y spectroscopies\, it enables us to identify a few critical factors affect
 ing the charge transfer dynamics at organic/electrode interfaces.\n\n\n\n\
