<div>Dear Xiaojun,</div>
<div id="AppleMailSignature"><br>
</div>
<div id="AppleMailSignature">I believe you will find there to be many facilities that can provide access to instruments capable of KPFM measurements, CNSI at UCLA included. </div>
<div id="AppleMailSignature"><br>
</div>
<div id="AppleMailSignature">Keep in mind that while most commercial AFMs can operate in this mode there are specific considerations that must be taken into acct, namely your resolution requirements both spatially and with respect to the contact potential/surface
potential difference you hope to measure. The frequency modulated mode provides better sensitivity but is not as readily available as a standard mode on many commercial AFMs. Amplitude modulation, like what is used in traditional Kelvin probe measurements,
is the industry standard but does limit one's ability to resolve features smaller than 100s of nanometers. Finally, this measurement can be quite sensitive to measurement artifacts. To get reliable data you should identify a resource that not only provides
the appropriate equipment but also the requisite expertise to provide training and/or analysis services. </div>
<div id="AppleMailSignature"><br>
</div>
<div id="AppleMailSignature">UCLA is quite far from you, so I would recommend looking either at UIUC or ORNL as a starting point. </div>
<div id="AppleMailSignature"><br>
Best,</div>

<div id="AppleMailSignature">Some AFMs (atomic force microscope) equip Kelvin probe measurement function. The Asylum Research AFM systems in CNS at Harvard has SKP capability and they are open to public. Please feel free to let your user to contact me for more
details.</div>
