TL;DR: In this article, the authors calculate and measure the noise characteristics of self-sensing quartz sensors and find four noise sources: deflection detector noise, thermal noise, oscillator noise, and thermal drift noise.

TL;DR: Superconductivity of nanosized Pb-island structures whose radius is 0.8 to 2.5 times their coherence length was studied under magnetic fields using low-temperature scanning tunneling microscopy and spectroscopy.

TL;DR: In this article, the adsorption of two kinds of porphyrin (Cu-TBPP) and perylene (PTCDA) derived organic molecules was studied by noncontact force microscopy in ultra-high vacuum, the goal being the assembly of ordered molecular arrangements on insulating surfaces at room temperature.

TL;DR: High-resolution noncontact atomic force microscope images were successfully taken on the Ge105-(1 x 2) structure formed on the Si105 substrate and revealed all dangling bonds of the surface regardless of their electronic situation, surpassing scanning tunneling microscopy, whose images strongly deviated from the atomic structure by the electronic states involved.

TL;DR: Unprecedented high spatial resolution was achieved by setting the detection force at a small value and by reducing background forces due to the long-range interactions with the small oscillation amplitude of the cantilever and sharp probe tip.
