Dear Dr. Stephen,

I am using Bruker Dimension system for d33 and d31 measurement of ZnO nano rods. There is two PE loop curve (phase vs tip bias) and two butterfly loops (amplitude vs tip bias). Can you tell me in details and which one plot will give d33 and which one give d31. There is two feed back circuit horizontal and vertical, how they are related with amplitude-1 and amplitude-2 as well as d33 measurement. In my measurement amplitude-2 is giving higher d value.
I need your support in the understanding of the measurement in details. I am in final year of my PhD Engg. at IISc Bangalore, India.

Looking forward to your kind reply.

With regards
Nagendra

Hi Stephen,

                      Just reviewed you AFM video as of yesterday Monday 29th of Oct, been of a mechanical background and worked with surface finishes, developed to industrial automation, mechatronic studies and now nano studies now obtaining a BSc in manufacturing Engineering with project work of micro assembly gripper, for mono fibre grasping using flexures a closed loop pizeo actuator with capacitive sensors feedback.Hence I get the van der waal forces test method, while Alex in this case was using a cantilever with a light detector.                                    Is tip technology of the AFM the biggest part of the learning curve?

Hi Stephen, 

I want to install Nanoscope software on my MacBook. Is the Mac version of Nanoscope available?

Thanks,

Manpuneet
