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.

Previous works:

• Content-based
• Diagrams are 2D→might be

incomprehensive for the public and new investigators For this project:

• 3D diagrams →clear

image of the electric models can be presented to the public.

• Different types of

perovskite materials

Introduction

Introduction

Scope

• 3D

computing graphics software Blender to study the physical properties of ultra thin metal oxides. Assumption

• Schematics and working

principles of nanoelectronics can be represented using 3D diagrams.

Introduction

• Constraints in the software’s

modelling techniques and for aesthetics needs.

• Simulations and graphical

depictions of ultra thin metal

• xides may differ slightly from

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 LaAlO3 /SrTiO3 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
• perations

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
• rder to accurately present

the material’s physical property.

Results

Results

• 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 SrTiO3 Figure 2.1 Two-dimensional figure of SrTiO3

Results

• Although they are too small for

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 SrTiO3 Figure 2.1 Two-dimensional figure of SrTiO3

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 2.2 Three-dimensional modelled figure of SrTiO3 Figure 2.1 Two-dimensional figure of SrTiO3

Limitations

• Could only simulate the side view similarly

as they did for the front view: ○ May involve inaccurate depiction of the actual metal oxide.

• For moisture air:

○ Quantity of water molecules present in the actual metal oxide is indeterminate.

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.
