AIST Near-Field Optical Microscope
Cryovac Low Temperature STM/AFM
The Createc Low Temperature STM/AFM is a customized microscope that operates in an ultra high vacuum and at temperatures between 4 K and 370 K. The instrument is a combination of PAN-type slider STM with highest spectroscopy performance (1 meV energy resolution), scan range over 800 nm at 4K, and a q plus AFM that allows to perform ultra high resolution AFM. In addition, we incorporated optical access to both couple light directly into the tunnel junction or collect light from the tunnel junction, enabling to study the local electronic structure with atomic resolution while being optically excited. Both, STM and AFM provide subatomic spatial resolution due to the outstanding stability (dz<1 pm) AFM and STM can per operated simultaneously without cross-talk using constant frequency or constant height control.
Park NX10 Photocurrent Microscope Under Controlled Environment
The Park NX10 is a very easy to use AFM, which includes all typical AFM, topography modes, Kelvin Probe Microscopy, etc. The main use of this microscope is to perform photo current and photo voltage measurements on photo active materials. Two additional specific features that attract users is the set up in a low noise glove box, allowing samples, such as perovskites that can photo oxidize, to be measured using this microscope, plus a special tip approach mode, which approaches the tip at a single measurement pixel, avoiding almost all topography – photo current signal convolution when measuring samples with large topographic features.
