Q. Consider the following statements:
1.Rashba splitting, also known as the Rashba effect, is a phenomenon where the spin-splitting of electronic energy levels occurs in a material due to the spin-orbit interaction.
2.Spintronics combines concepts from physics, materials science, and electrical engineering.
3.Spintronics involves harnessing the energy produced by the rotational motion of spinning objects, such as wind turbines, to generate electricity.
Which of the statements given above are correct?

[A] 1 and 2 only

[B] 2 and 3 only

[C] 1 and 3 only

[D] 1, 2 and 3

Answer: A

Notes:

Explanation –

Statements 1 and 2 are correct. Rashba splitting, also known as the Rashba effect, is a phenomenon where the spin-splitting of electronic energy levels occurs in a material due to the spin-orbit interaction. Spintronics combines concepts from physics, materials science, and electrical engineering.

Statement 3 is incorrect. Spintronics, short for “spin transport electronics,” is an emerging field of science and technology that explores the intrinsic spin of electrons as well as their fundamental electronic charge. Unlike traditional electronics that rely solely on the charge of electrons, spintronics utilizes both the charge and the spin of electrons for various applications.
