in barrier tunneling, if voltage is applied between two different materials, for eg Cu and Al and then the polarity is inversed, will there be any difference in the tunneling current?

Tunneling current in barrier tunneling refers to the flow of electrons through a potential barrier between two conductors. This phenomenon occurs due to the quantum mechanical effect of tunneling, where electrons can pass through a barrier that they do not have enough energy to overcome in classical physics.
Polarity reversal refers to the change in direction of electric current flow. In the case of Cu & Al, when the polarity is reversed, the tunneling current will also reverse direction. This can have a significant impact on the performance and functionality of devices that utilize barrier tunneling, such as diodes and transistors.
The tunneling current in barrier tunneling can be influenced by several factors, including the thickness of the barrier, the potential difference between the two conductors, and the properties of the materials used. Additionally, external factors such as temperature and electric field strength can also affect tunneling current.
Cu & Al are commonly used as conductive materials in barrier tunneling devices. They are often chosen due to their properties, such as low resistivity and good thermal and electrical conductivity. These properties allow for efficient tunneling current flow and make Cu & Al ideal for use in electronic devices.
Tunneling current in barrier tunneling has many practical applications in the field of electronics. It is used in the construction of diodes, transistors, and other electronic devices that rely on the flow of current through a potential barrier. It also plays a crucial role in the development of new technologies, such as quantum computing and tunneling field-effect transistors (TFETs).
