Special Issue Information

Dear Colleagues,

The continuous evolution of micro-electro-mechanical systems (MEMSs) and micro-electro-optical- mechanical systems (MEOMSs) has significantly impacted the field of sensor design, offering unprecedented capabilities in precision sensing, actuation, and control.

Within the domain of scanning probe microscopy (SPM), the integration of advanced MEMSs into MEOMSs has brought forth a new era of high-resolution imaging, manipulation, and sensing on the nanoscale level. By leveraging the unique characteristics of MEMSs and MEOMSs, researchers and engineers have been able to develop novel scanning probe technologies that push the boundaries of spatial resolution, sensitivity, and multifunctionality. As a result, SPM techniques, including atomic force microscopy (AFM) and scanning near-field optical microscopy (SNOM), have undergone remarkable enhancements, opening up new avenues for exploring biological systems, understanding material properties, and advancing nanotechnology applications.

This Special Issue aims to provide a platform for researchers to share their latest findings, technological advancements, and innovative applications at the intersection of MEMSs/MEOMSs and scanning probe microscopy within the sensor community. Through this collection of contributions, we seek to foster collaboration, inspire new research directions, and propel the ongoing development of MEMS/MEOMS-based sensor technologies for SPM and beyond.

Atomic Force Microscopy (AFM) is an advanced imaging technique which features nanoscale resolution and the ability to work under physiological conditions on soft samples. Modern AFM systems offer easy access to Dynamic Mode imaging which reduces the tip–sample interaction and increases the effective resolution. However, the intrinsic nature of this driving strategy induces a trade-off between three different aspects: the scanning speed, an accurate topography reconstruction and weak interaction forces. The impact of this inherent trade-off is especially evident when imaging samples with steep and deep valleys, and artifacts are often created in the reconstructed topography. This phenomenon, known as parachuting, rapidly worsens at faster speeds. In this paper, a new strategy is proposed for limiting parachuting artifacts, based on an adaptive driving strategy, which can be easily implemented as an add-on to commercial AFM systems. The suggested method has been tested on grid samples, and it enhances the nano-imaging quality by effectively reducing artifacts in the topography. Full article

One of the most advanced and versatile nanoscale diagnostic tools is atomic force microscopy. By enabling advanced imaging techniques, it allows us to determine various assets of a surface, including morphological, electrical, mechanical, magnetic, and thermal properties. Measuring local current flow is one of the very important methods of evaluation for, for instance, photovoltaic materials or semiconductor structures and other nanodevices. Due to contact areas, the current densities can easily reach above 1 kA/m2; therefore, special detection/measurement setups are required. They meet the required measurement range, sensitivity, noise level, and bandwidth at the measurement scale. Also, they prevent the sample from becoming damaged and prevent unwanted tip–sample issues. In this paper, we present three different nanoscale current measurement solutions, supported with test results, proving their performance. Full article
