An AFM configuration equipped with two different actuators for the vertical movement of the sample has been implemented. The Z actuator of a 3D nano-positioning stage, Tritor100, is the first element. For the second, faster, vertical actuator PV1 we designed and realized a flexural structure that includes a miniature piezo actuator with about 1 µm displacement range and a mechanical resonance at 7.5kHz . Both the devices act changing the vertical position of the sample.

Abstract
An AFM configuration equipped with two different actuators for the vertical movement of the sample has been implemented. The Z actuator of a 3D nano-positioning stage, Tritor100, is the first element. For the second, faster, vertical actuator PV1 we designed and realized a flexural structure that includes a miniature piezo actuator with about 1 µm displacement range and a mechanical resonance at 7.5kHz . Both the devices act changing the vertical position of the sample.File in questo prodotto:
