Origin of electronic bands in materials. Explain how electronic energy bands arise in materials. The periodic potential
Question:
Origin of electronic bands in materials. Explain how electronic energy bands arise in materials. The periodic potential in a one-dimensional lattice of spacing a can be approximated by a square wave which has the value U0 =-2 eV at each atom and which changes to zero at a distance of 0.1a on either side of each atom. Describe how you would estimate the width of the first energy gap in the electron energy spectrum.

I have been a tutor for the past 5 years. I have experience working with students in a variety of subject areas, including computer science, math, science, English, and history. I have also worked with students of all ages, from elementary school to college. In addition to my tutoring experience, I have a degree in education from a top university. This has given me a strong foundation in child development and learning theories, which I use to inform my tutoring practices.
I am patient and adaptable, and I work to create a positive and supportive learning environment for my students. I believe that all students have the ability to succeed, and it is my job to help them find and develop their strengths. I am confident in my ability to tutor students and help them achieve their academic goals.
