The book "Microelectronics Fabrication by Self Assembly of Nanoparticles" offers a comprehensive examination of the self-organization of nanoparticles for the fabrication of microelectronic devices. It highlights the natural processes that lead to the arrangement of materials in structured and ordered forms. By deliberately altering the layer stacks and material properties, the electrical and optical characteristics of the produced devices can be significantly influenced. The author, Muhammad Irfan Abid, discusses the multilayer devices that are created through a layer-by-layer self-assembly process using colloidal gold and zinc sulfide nanoparticles. A central theme of the book is the control of the pH level of the colloidal solutions used during the assembly process to optimize the properties of the deposited layers. Additionally, complex conduction phenomena in these devices are addressed, exploring similarities between the threshold voltages and current values of various array structures. The experimental results provide valuable insights for engineers and scientists in the field of microelectronics and open up perspectives for future manufacturing techniques of electronic circuits and devices.
