Direct photodesorption of atomic hydrogen from S1(100) at 157 nm: experiment and simulation
Article Abstract:
A study was conducted to study the direct photodesorption mechanism of atomic hydrogen from silicon (Si)(100). Results indicate that atomic hydrogen photodesorbs from Si-(100)-(2 x 1):H monohydride surface under 157 nanometer laser irradiation. It was also observed that the transition dipole moment is oriented along the H-Si bond directions. The findings of the study may be useful in the development of resistless photolithography and semiconductor technology.

Two-photon photoemission study of heterogeneous electron transfer: C6F6 on Cu(111)
Article Abstract:
A study was conducted to analyze photoinduced heterogeneous electron transfer using two-photon photoemission spectroscopy. The energetics in photoinduced heterogeneous electron transfer was examined in monolayer and bilayers of hexafluorobenzene on Cu(111). Experimental results indicated that molecular resonance correlate with an electron transfer to an unoccupied molecular orbital found at 2.9 eV.

The nature of electronic contact in self-assembled monolayers for molecular electronics: evidence for strong coupling
Article Abstract:
Two-photon emission has been used to create the interfacial electronic structure in a model self-assembled monolayer system. It was found that, relative to the vacuum, the highest occupied molecular orbital was located at -6.4eV.
