Imaging and Surface Science Laboratory

TEM image

Cu2ZnSn(S,Se)4 nanoparticles, which are part of the energy research program of Dr. Amy Prieto. The research is being conducted by Dr. Lasantha Korala. Images were taken with the new JEM-2100F TEM.

The Imaging and Surface Science laboratory has several tools for examining materials and can provide high resolution (angstrom to micron scale), detailed pictures of surfaces and thin films, micro-structural crystallographic information (from electron diffraction data), and X-ray spectral data including elemental analysis of small features.

All of our instruments are open-access to CSU students and researchers, after having received training by CIF staff. Please register as a new user to schedule training, and reserve instrument time by using the online calendars. Use of the TEM requires more assistance due to the complexity of the instrument.

 

Electron microscopy instruments

JEOL JSM-6500F SEM

JEOL JSM-6500F field emission scanning electron microscope (FESEM) equipped with the In-Lens thermal field emission electro gun (TFEG).  This high resolution tool has a multi-purpose specimen chamber and a motorized, automated stage.  The SEM is equipped with a Thermo Electron energy dispersive X-ray spectrometer (EDS) for qualitative and quantitative elemental analysis, and with a Nabity e-beam lithography patterning system (NPGS). The NPGS in conjunction with our FESEM allows for patterns to be written with our SEM that are just a few tens of nanometers in width.

JEM-2100F TEM

JEOL JEM-2100F transmission electron microscope (TEM) with HR pole piece, STEM and electron diffraction cameras for studying both hard and soft materials with atomic scale resolution. Also available is a Fishione model 1070 nanoclean plasma cleaner for TEM sample prep.

XPS Operating Instructions

  • PE-5800 X-ray Photoelectron Spectroscopy (XPS), also known as Electron Spectroscopy for Chemical Analysis (ESCA) – a technique to X-ray Photoelectron Spectroscopyinvestigate the chemical composition of surfaces (elemental identity, chemical state, and quantity of elements). Can also provide useful information about depth profile and thickness (<10 nm) of thin films. Some key features of the XPS in our facility include:
    • Accurate quantitative chemical state analysis of surfaces
    • Superior thin film characterization (sputter depth profiling)
    • Superior angle dependent analysis (non-destructive depth profiling)
    • Effortless analysis of electrically insulating samples
    • Scanning Auger Microscopy (SAM) with submicron spatial resolution
    • Dual beam charge neutralization technology provides “hands off” charge neutralization on electrically insulating samples
  • Bruker Dektak XT Stylus Profilometer for measuring a material surface’s profile and quantifying its roughness.
  • Nanoscience 2 AFM with both continuous and tapping mode tips, nanometer or better resolution possible
  • Krüss DSA10 Drop Shape Analysis System Contact Angle Goniometer (CAG) used to measuring contact angles using the sessile drop technique. The DSA10 is capable of measuring static contact angles (still camera mode) or time dependent contact angles (video camera mode) on flat substrates using a wide variety of probe liquids.
