For high accuracy LUMO levels measurement and unoccupied density of states evaluation
LEIPS：Low-Energy Inverse Photoemission Spectroscopy
LE-１ series |
Achieves high-precision LUMO levels (electron affinities) measurement without damage to organic materials for the first time.
Furthermore, we are expanding the field of activity to inorganic semiconductors,
polymer materials, etc.

■Feature
| ● |
The measurement energy resolution less than 0.5 eV . |
|
| ● |
Equipped with the LEIPS software that realizes easy operation (measurement & energy evaluation) |
|
| ● |
Stable low-energy electron emission is realized by a dedicated electron gun and a dedicated activation process. |
|
| ● |
Measurement point magnetic field zero adjustment mechanis |
|
| ● |
The subtrate holder transfer mechanism that facilitates docking with various systems |
|
| ● |
The attached carrier BOX allows the substrate to be attached anddetached without exposure to the atmosphere. |
|
| ● |
Various options: High-precision substrate tilting mechanism, vapor deposition mechanism, etc |
|
|
 |
■LE-1 can support Multi- systemization as standard.
We have a track record of docking with photoelectron spectrometers (XPS, UPS), PYS (photoelectron yield spectroscopy), etc.
