Single Self-assembled Icosahedral Protein Cage

Self-assembling proteins are candidates as building blocks for “smart” biomaterials that can potentially exploit the rich structural and functional properties of proteins. This has led to the design of new self-assembling protein structures such as these icosahedral protein cages. Since icosahedral protein cages can encapsulate large volumes, they are often used for vaccine design and […] Read more

Latent Images of Exposed EUV Photoresist

The development of EUV (extreme ultraviolet) resist materials is critical to producing semiconductor devices with the smallest feature sizes. Understanding the light-induced chemistry of EUV photoresist and its impact on the quality of EUV lithography would help engineers to optimize this important technology. Photo-induced Force Microscopy (PiFM), with its capability to detect nanoscale chemical properties, is well suited […] Read more

Silicon Strain in Semiconductor Devices

PiFM Imaging of Local Strain in Silicon at Individual FIN Level Carrier mobility enhancement through local strain in silicon is a means of improving transistor performance. In order to effectively validate device design and process conditions, a direct measurement of strain in the nanoscale is desired. Here, we demonstrate true nanoscale strain mapping via PiFM […] Read more

PiFM Perovskite Solar Cell (PSCs)

Collaboration on PSCs Published in Advanced Materials

PiFM analysis of high-efficiency perovskite solar cells (PSCs): In collaboration with some leading researchers in high-efficiency polymer solar cells, Molecular Vista performed PiFM imaging on several samples. Transient absorption measurements and PiFM analysis investigated the effect of thermal-annealing on the active layer morphology and photo-voltaic performance of high-efficiency conjugated polymer donors for perovskite solar cells […] Read more
