Application Notes: SPM 150 Aarhus with KolibriSensorTM

ANote: NC-AFM Atomic Resolution Au(111) 
NC-AFM imaging of the Au(111) surface revealing atomic steps, the herringbone reconstruction, and atomic resolution. Furthermore the acquisition of a two-dimensional force map F(x,z) on Au(111) is shown.  
  
TNote: Atom Tracking Module for Drift-free Measurements at Room Temperature 
A quick demonstration of the atom tracking technique, which allows one to have literally thermal drift-free imaging, reliably, even at room temperature.  This is achieved with the combination of the KolibriSensor™ and the Nanonis Control System. 
  
ANote: On-the-Fly Switching Between STM and AFM Topography Feedback 
On-the-fly switching between STM and nc-AFM feedback mode is demonstrated, which enables atomic scale studies of the same surface area, imaged in both feedback modes.  Applications of feedback mode switching for identification of atomic size defects and in large-scale topographic imaging are presented. 
  
ANote: Atomic Resolution NC-AFM on Si(111)-(7x7) 
The excellent signal to noise ratio of the KolibriSensor™  in combination with its high resonance frequency of 1 MHz enables highest resolution constant detuning NC-AFM imaging on Si(111)(7x7) at  scanning speeds being more than one order of magnitude faster than conventional AFM. The high stability of the SPM 150 Aarhus allows for imaging of vacancies, adsorbates and atomic steps with atomic resolution. Furthermore imaging in the repulsive tip-sample interaction regime is demonstrated. 
  
TNote: Reproducibility of the Approach Mechanism 
Data showing the reproducibility of the Approach Mechanism of the SPM 150 Aarhus with KolibriSensor™.
 
  
ANote: 3D Force Mapping 
Recent results and a discussion of site specific force spectroscopy on insulators:  Acquisition of two-dimensional force maps F(x,z) on KBr(001) at room temperature. 
  
TNote: SPM 150 Aarhus with KolibriSensor™ 
The SPM 150 Aarhus with KolibriSensor™ combines the extreme stability of the Aarhus design with state-of-the-art noncontact atomic force microscopy (NC-AFM) techniques. The KolibriSensor™, based on the piezoelectric length extension resonator, enables the scientist to study every surface regardless of its conductivity with outstanding resolution at the atomic scale.
 
  
ANote: Atomic Resolution on Insulators 
The excellent performance of the SPM 150 Aarhus with KolibriSensor™  is demonstrated by atomic resolution noncontact atomic force microscopy (NC-AFM) imaging on insulating KBr(001). 
  
ANote: SubAngstrom Oscillation Amplitudes 
Benchmark atomic resolution measurements on insulating KBr(001) with oscillation amplitudes down to 30 pm at room temperature are presented. These results demonstrate the outstanding imaging performance and extraordinary stability of the KolibriSensor™.
