Note: Among the common methods of producing nanostructures, stretching, molding, fuzzy separation, self-assembly and electrospinning, electrospinning has many advantages such as ease of production, possibility of industrialization, ability to control the raw material dimensions of nanochips and nanotransistors.
Most chips and nanochips are made of silicon. By applying the appropriate voltage (threshold voltage) to the silicon solution, the repulsive force overcomes the surface tension of the silicon and a jet is formed. By evaporating the solvent from the jet, the liquid-to-solid phase changes and nanoparticles of the chips are formed. Many parameters affect the characteristics of nanostructures produced by this method, the most important parameters are the distance between the needle and the collector, the applied voltage, the flow rate and the concentration of silicon solution; By changing these parameters, the optimal dimensions of nanochips can be achieved. The diameter of nanostructures is linearly related to the flow rate and distance and non-linearly related to the potential and concentration of silicon solution in the production of nanochips and nanotransistors. With increasing distance and electrical potential, the diameter of nanostructures decreases and with increasing current rate and electrical potential, it increases. In the production of nanoparticles and nanotransistors, the electric field reaches a critical value or threshold when the repulsive force overcomes the surface tension. The jet first moves in a linear pattern, then slowly moves away from the linear pattern, forming a complex shape along the path to the collector. The structure and structure of the production of nano-chips and nano-transistors and the length of the jet are proportional to the applied voltage. The structure of the Taylor nano-cone changes from convex to concave by changing the field strength and consequently (jet charge density).
Note: The nano -transistor is one of the most important nano-electrical components that has functions such as circuit amplifier, power supply, etc. And is used in the internal structure and structure of chips and nano-chips.
The shrinkage of components in microelectronic systems and circuits has led to significant growth in the industry in recent years. The industry is growing so fast that as the number of components gets smaller, the number of transistors per unit area of each semiconductor chip and nanocip has increased. Reducing the dimensions of these components can reduce the consumption of raw materials and energy, reduce the cost of these components and increase their speed and efficiency. Therefore, the construction and development of electronic tools with smaller dimensions and higher speed and efficiency has become more important day by day. Lithography is one of the most common methods for making electronic circuits. With the help of this method, structures with precision and dimensions of 01 nanometers can be made. Finding techniques that can be used to industrially produce these components (nanochips and microchips).
Conclusion :
Among the common methods of producing nanostructures, stretching, molding, fuzzy separation, self-assembly and electrospinning electrospinning have many advantages such as ease of production, possibility of industrialization, ability to control the dimensions of raw materials of nanocips and nanotransistors.
