Electrical AFM · Nano-Observer II & Galaxy Dual Controller

Kelvin probe and conductive AFM that read the whole sample

HD-KFM™ III maps topography and surface potential in a single pass. ResiScope™ III maps resistance from 10² to 10¹² Ω in one scan, where conductive AFM saturates. On a new Nano-Observer II, or on the AFM you already have.

Our application team tells you which mode fits your sample and can run test measurements on it.

Why it is different

Two limits of standard electrical AFM, removed

Surface potential · KPFM

Single pass, not lift mode

Lift-mode KPFM reads the potential on a second pass, tens of nanometres above the surface, so it averages and picks up the topography. HD-KFM™ III uses the cantilever’s second eigenmode and records topography and potential in the same pass, with the tip close to the surface.

Graphene layers, same area: standard lift-mode KFM and single-pass HD-KFM, with line profiles
HD-KFM™ sharper layer edges and flatter levels than lift-mode KFM, same graphene area
Lift-mode KPFM versus single-pass HD-KFM
Lift mode reads on a second pass, above the surface; HD-KFM™ in the same pass

Current · conductive AFM

Ten decades, not one amplifier gain

A conductive-AFM amplifier covers one slice of the current range. On this battery electrode it clips every conducting particle at 10 nA. ResiScope™ III adjusts its gain in real time and keeps every phase in range.

FAQ

Frequently Asked Questions

What is the difference between KPFM and HD-KFM?

Standard KPFM often maps surface potential on a second pass, lifted above the topography line, so the potential is averaged and can pick up topographic artifacts. HD-KFM records topography and surface potential together, in one pass, using the second eigenmode of the cantilever. On graphene it separates one to four layers by their work function.

How is ResiScope different from conductive AFM?

Conductive AFM measures current and saturates when the sample spans a wide resistance range. ResiScope™ III covers 10² to 10¹² Ω in a single scan, so an insulating region and a conducting region of the same sample both stay in range.

Can HD-KFM and ResiScope be added to an existing AFM?

Yes. The Galaxy Dual Controller upgrades Bruker MultiMode and Dimension 3000/3100 AFMs, and Molecular Imaging, Agilent and Keysight 5100, 5400/5420, 5500, 5600LS and PicoSPM systems. It keeps the AFM’s existing modes and adds HD-KFM, ResiScope and Soft Interaction Control.

How much does an electrical AFM cost?

There is no public price list: the quotation depends on whether you need a Nano-Observer II or a controller upgrade, and on which modes you add. Send the measurement you need and the team replies with a quotation.

Can CSInstruments measure my sample before I buy?

Yes. Send a short description of the material and the measurement — surface potential, resistance, or both — and the application team recommends a mode and can run test scans.
