Sample vessel retention structure for scanning probe microscope

A sample vessel retention mechanism for an inverted microscope having an optical objective and a scanning probe microscope (SPM) head. The inverted microscope includes a platform for supporting a sample vessel, in which is formed an aperture sized to provide a passage for the objective of the inverted microscope to approach the sample vessel from below. The retention mechanism provides a vacuum region formed in the platform, with the vacuum region being barometrically coupled with a vacuum generator. Establishment of a vacuum in the vacuum region prevents or substantially reduces oscillation of the sample vessel floor in an operating frequency range of the SPM head.

Scanning probe microscope and its sample holder

This sample holder for a scanning probe microscope is constituted of (1) a container that retains a liquid and (2) a flat-plate-shaped upper cover that covers an upper opening of the container and that has a narrow slit above the position where a sample is placed. In the upper cover, the slit has a slit width with which a thin film of the liquid is formed over the upper surface of the sample when the liquid fills the space between the container and the upper cover. The thin film of the liquid has a film thickness smaller than the distance between the upper surface of the sample and the upper cover.

Head-integrated atomic force microscope and composite microscope including same

An object of the application is to provide a head-integrated for an atomic force microscope capable of realizing minimization of a weight and a volume and improvement of structural stability by optimizing a head structure of the atomic force microscope. Another object of the application is to provide a head-integrated atomic force microscope capable of being utilized for imaging a large-area sample by enabling high-rate head scan due to dynamic characteristics improved by mounting the integrated-head described above. Still another object of the application is to provide a composite microscope including a head-integrated atomic force microscope, capable of performing high-rate position search and imaging and performing precise observation of a three-dimensional shape up to an atomic image level in a region of interest by combining the head-integrated atomic force microscope having the improved dynamic characteristics as described above and an electron microscope or an optical microscope with each other.

Scanning probe microscope with a reduced Q-factor

A scanning probe microscope is provided comprising a scanning probe (10), a holder (5) for holding a sample (SMP) in an environment free from liquid. A scanning arrangement (20) is provided therein for inducing a relative motion of the scanning probe (10) with respect to said sample (SMP) along a surface of the sample (SMP). A driver (30) generates a drive signal (Sd) to induce an oscillating motion of the scanning probe (10) relative to the surface of the sample to be scanned. A measuring unit (40) measure a deflection of the scanning probe (10), and provides a deflection signal (S) indicative for said deflection. An amplitude detector (50) detects an amplitude of the oscillating motion as indicated by the deflection signal (S) and provides an amplitude signal (Sa) indicative for the amplitude. The scanning probe (10) is at least partly arranged in a liquid (L) to dampen motion of said scanning probe, and therewith has a quality factor Q which is less than or equal than 5. The scanning probe (10) is accommodated in a casing (90) comprising said liquid (L), the scanning probe (10) comprising a flexible carrier (11), the flexible carrier having a movable part provided with a tip (12), which tip (12) extends through an opening (91) in said casing.
