In a semiconductor crystal, the atoms are primarily held together by covalent bonds. Covalent bonding is a fundamental chemical bond where atoms share electrons, allowing them to achieve greater stability. This is essential in semiconductors, as the ability to form these bonds directly influences the electrical properties, band structure, and overall behavior of the material.

Here's a brief explanation of the options:

1. Covalent Bonds: This is the correct answer. In semiconductors like silicon, each atom shares electrons with its neighboring atoms, forming a stable crystal lattice.

2. Atomic Glue: This term isn't a scientific term and doesn’t represent the forces at play in a semiconductor.

3. Subatomic Particles: While semiconductors are made of atoms comprising subatomic particles (electrons, protons, and neutrons), this option does not directly describe how atoms in a crystal are held together.

4. The Valence Band: This refers to the energy band containing the valence electrons of the atoms, but it does not describe the bonding itself.

Final Answer

Covalent Bonds are the primary forces holding atoms together in a semiconductor crystal.
