Dear Mariam, How stiff (ballpark) is your ceramic sample? When you say the roughness is 0.5-2um what is the scan size that gives you that roughness? If you want to measure the modulus of a stiff sample, you must use a stiff cantilever. Question 1 will allow you to look in the manual and find the recommended...

You should choose a cantilever that is sensitive as possible, but does not cause the deflection measurement to saturate or become non-linear. The force is the spring constant times the deflection sensitivity times the detector voltage (F=K*Sd*V). If we know K for a given probe type and we know the approximate...

Innovation with Integrity Proprietary High-Contrast Probe Tips on Innova-IRIS AFM Enable First Complete Commercial TERS Solution April 2013 The single biggest issue preventing further adoption of the powerful Tip-Enhanced Raman Spectroscopy (TERS) technique is the lack of available high-performance probes...

No, there is no tip coating on OTESPA probes. The Al coating is backside only for better reflectivity. MESP or SCM-PIT probes are commonly used for KPFM. If you like the visible apex tip feature of the OTESPA probes, then you might also check out the OSCM-PT probes. Details for each can be found at Bruker...

Hi Mithun, Having the EFM HOLDER AND SCM-PIT tips are enough for you to perform surface potential on Multimode; you do not need to apply voltage externally. Surface potential measurement has been done on organic solar cell (BHJ) and its component materials; make sure you electrically connect the underlying...

Hi Sheila, The probe is critical for surface potential measurements, it is required to have a well defined work function and be robust. SCM-PIT probe from Bruker has a Pt-Ir coating which meets these criteria. Also Rocky Mountain Nanotech offers solid Pt probes (25Pt300B) which has the advantage that...
