Structural Characterization of Thin Films of Molecules on Solid Surfaces: Development of a Portable UHV Chamber to Bridge RHEED and SFG Spectroscopy Techniques
In surface science, it is often essential to visualize and obtain the structures of molecules at solid-liquid and solid-vacuum interfaces, etc. Each surface characterization method has its advantages and disadvantages, and there is no single technique that can provide all possible information about …

Experimental studies of evaporative cooling and Bose Einstein condensation in an optical trap
… transferred into a conventional MOT inside a UHV chamber with capture rates exceeding 10^8 atoms/s. After a loading time of 1s and a loading phase of 60 ms about 1% of the atoms are trapped in a tight CO2 Laser focus region. Evaporative Cooling is optimized by lowering the dipole trap depth …

Bose-Fermi mixtures of ultracold gases of dysprosium
… at 421, 741, and 1064 nm, the ultra-high vacuum (UHV) chamber, and the computer control that has produced a magneto-optically (MOT) and magneto-statically (MT) trapped Dy gas (Chapters 3, 4, 5). Despite the fact that Dy has a complex energy level structure with nearly 140 metastable states …

Excitation-Induced Ge Quantum Dot Growth on Si(100)-2X1 by Pulsed Laser Deposition
… on Si(I00) were grown in an ultrahigh vacuum (UHV) chamber (base pressure ∼7.0x10 <sup>-10</sup> Torr) by femtosecond pulsed laser deposition. The results show that excitation laser reduces the epitaxial growth temperature to ∼70 °C. This result could lead to nonthermal method to achieve low …

Variable Temperature Scanning Tunneling Microscopy Study of a High Temperature Superconductor Bi2Sr2CaCu2O8+d
We have used a custom-built scanning tunneling microscope (STM) to investigate the electronic states of a slightly underdoped high-TC superconductor Bi2Sr2CaCu2O8+d as a function of temperature. We have demonstrated for the first time that atomicallyresolved spectroscopic studies at elevated …
