| Abstract | Bimodal atomic force microscopy (AFM), where the first two flexural eigenmodes of the cantilever are simultaneously excited, is an extension of dynamic AFM to enhance the contrast of multicomponent materials. The effects of the operating parameters for both modes are explored by imaging a polymer blend of polystyrene (PS) and low-density polyethylene (LDPE) the in attractive and repulsive regimes. In this study, the phase and amplitude contrasts of the individual eigenmodes for bimodal AFM are quantitatively calculated using a statistical expression. Meaningfully, the higher free amplitudes of the second mode, which were chosen beyond the traditional values, show significantly better compositional contrast, particularly for the phase of the second mode. The phase contrast of the second mode increases by 3–10 times compared with that of the traditional results. The relationship between the contrast and amplitude ratio of the first mode is also researched experimentally in the bimodal mode. Virial and energy dissipation power for the corresponding modes are employed to explain the enhanced phase contrast physically. The meaningful results obtained are applicable to optimize the operating parameters of image contrast and study the surface morphology and properties of soft, even biological materials. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
