  • Re: Spring constant calibration in air - temperature

    Hi Sjoerd, It is generally assumed that the spring constant is constant with temperature. That is probably not precisely true (modulus and dimensions of materials like Si change a bit with temperature), but the variation should be small compared to the uncertainty in the measurement. If you want to investigate...

  • [FWD from LinkedIn] relation between working function and corrosion potential

    Being updated.... Marjan Kashfipour Research assistant at The University of Akron Hi all, is there anybody who can explain the relation of working function which is measured during KPFM mode of AFM and corrosion potential of the sample? I'm confused a little bit about it, some papers assume higher...

  • Re: Frequency Modulation

    Hi Zhuoyang, The Open Harware allows you to output the signals necessary to feed a FM detection "box" as well as allows you to use an external signal as "feedback". What you have to provide is any additional electronics required. Best, Stefan

  • ECAFM in liquid

    Do you make any specifically designed liquid cells for ECAFM where you cn place a cathode sample and test it? Also, is AFM supplied with potentiostat?
