What is nanoelectronics?

The term nanoelectronics refers to the use of nanotechnology in electronic components. These components are often only a few nanometers in size. Applications of such technology are usually found in transistors for carbon nanotubes, flexible electronic circuits, creating data storage chips, e-textiles and solar energy cells etc.

Introduction For this project: Previous works: ● 3D diagrams →clear ● Content-based image of the electric ● Diagrams are 2D→might be models can be presented incomprehensive for the public to the public. and new investigators ● Different types of perovskite materials

Introduction Assumption Scope ● Schematics and working ● 3D computing graphics principles of nanoelectronics software Blender to study can be represented using 3D the physical properties of diagrams. ultra thin metal oxides.

Introduction ● Simulations and graphical ● Constraints in the software’s depictions of ultra thin metal modelling techniques and for oxides may differ slightly from aesthetics needs. actual physical property (colour, shape, orientation and position of particles).

AIMS/OBJECTIVES Visualize complex scientific concepts in nanoelectronics by designing 3-dimensional (3D) images.

Literature Review Electronic Phase Separation at the LaAlO 3 /SrTiO 3 Interface ● Emerged as one of the most scientifically and technologically interesting material systems. ● Perovskites display “a broad range of physical manifestations, including charge-ordered insulator, double-exchange ferromagnet and high-temperature superconductor” .

Methodology

Methodology ● Possible graphic softwares: Blender, autoCAD, Cinema 4D ● Use the software skillfully, before moving on to create 3D graphic models for perovskite materials. ● Tutorial lessons on Blender online or YouTube → more direct and comprehensive operations. ● Scaling, rotating, shifting and editing meshes. ● Memorise and make use of the shortcut keys to improve working efficiency.

Methodology ● Add grid mesh and enter edit mode. ● Basic operations such as dragging, rotating and scaling vertices or faces of the mesh is needed to produce a more accurate and aesthetic structure.

Methodology ● Diverse shapes and size in order to accurately present the material’s physical property.

Results

Results Figure 2.1 Two-dimensional figure of SrTiO 3 ● Products using Nanoelectronics are made of tiny molecules in 3D, sometimes with many water molecules attached with it. Figure 2.2 Three-dimensional modelled figure of SrTiO 3

Results ● Although they are too small for Figure 2.1 Two-dimensional figure of SrTiO 3 human to see, we can use computing to represent its minor structure for further studies and investigations. Figure 2.2 Three-dimensional modelled figure of SrTiO 3

Limitations

Limitations ● 2D images→only depicts front view; ● 3D models→both front and the side view of the material, for which the latter is unknown. Figure 2.1 Two-dimensional figure of SrTiO 3 Figure 2.2 Three-dimensional modelled figure of SrTiO 3

Limitations ● Could only simulate the side view similarly as they did for the front view: Figure 2.1 Two-dimensional figure of SrTiO 3 ○ May involve inaccurate depiction of the actual metal oxide . ● For moisture air: ○ Quantity of water molecules present in the actual metal oxide is indeterminate. Figure 2.2 Three-dimensional modelled figure of SrTiO 3

Conclusion

Conclusion ● Simple methodology of nanoelectronics can be represented using 3D softwares. ● Only the front view diagram was given for each model. ● Affect the accurate visual depiction of the material. ● Require further investigation and research if people would like to know more about this technology.
