**vibrations** in machines, vehicles and aircraft. A new three-dimensional **lattice** structure developed by ETH scientists could now expand the possibilities of **vibration** absorption. Led by Chiara Daraio, Professor of Mechanics and Materials, the researchers made the structure, which has a **lattice** spacing of around 3.5 mm, out of plastic using a 3D.

(a) Assume the structure is a Bravais **lattice** with one C atom per primitive unit cell. Take an arbitrary C atom as the origin, and connect it to a nearest neighbor with a vector d. Then, dcan be defined as a primitive vector, therefore nd must be a **lattice** vector. Obviously, −dis not in this structure.

**Mono-atomic** **lattice** is a special case of diatomic where the unequal masses become equal. Our dispersion curve clear depends on the ratio of the masses or in the electrical analogue case, the ratio of the capacitance and so does the frequency gap.If you increase the difference in the masses, the band gap grows. We study the magnitude of zero-point **vibration** in one-component crystals. For the crystals whose constituent atoms share the same bonding geometry, we prove the existence of a characteristic temperature, T0, at which the magnitude of zero-point **vibrations** equals to that of the excited **vibrations**. Within the Debye model T0 is found to be ~1/3 of the Debye temperature.

Atomic **Vibrations**: microscopic scale Assumptions: 1. Adiabatic approximation- assume electrons are attached rigidly to the nucleus. 2. Assume the amplitude of the **vibrations** is small. 3. Harmonic approximations- terms of order higher than x2in the interatomic potential are neglected. 1. Harmonic approximation.

**LATTICE** **VIBRATIONS** 3. **LATTICE** **VIBRATIONS** •Atoms in **lattice** are not stationary even at T= 0K. •They vibrate about particular equilibrium positions at T= 0K ( zero-point energy). •For T> 0K, **vibration** amplitude increases as atoms gain thermal energy. 3.1 Sound Waves •Sound waves travel through solids with typical speeds ~ 5(km/s).

that the diatomic **lattice** exhibit important features different from the **monoatomic** case. Fig.3 shows a diatomic **lattice** with the unit cell composed of two atoms of masses M1 and M2 with the distance between two neighboring atoms a. Fig.3 We can treat the motion of this **lattice** in a similar fashion as for **monoatomic** **lattice**. However, in this.
