The course is addressed to the students that deal with crystalline solids. It is intended to illustrate the thermodynamic functions derived from the assumption of a simple ball and stick model. The course partially overlaps with the classical courses of Solid State, however, it considers the aspects usually left aside but of considerable practical value.
The course is intended to be BASIC and covers the following topics:
- TD State Parameters, Exchange Processes &State Functions for a set of linked atoms.
- Thermal equilibrium of a crystal
- Interpretation of the 2nd law of thermodynamics in a crystalline solid
- Internal Energy and Heat Capacity of a crystal
- Thermodynamic equilibrium of crystals under heat flow control and temperature control
- Vacancies/Point defects
- Thermodynamics and kinetics of Liquid to Solid Phase Transformations
- Polymorphic Transformations in Crystals. Nature of the hysteresis in phase transformation
- Polymorphic Transformation in nano-rods and other systems without or minimal mechanical constraints. Outline of the effect of constraints.
The primary objective of the course is to show that the observable properties, particularly, thermal and mechanical are a direct reflection of the properties of chemical bonds and that the properties are interdependent (cannot be changed independently)
- Submitting assignments is strongly recommended but not mandatory. Those who will submit less assignments will have the contributions to the final grade adjusted accordingly.
- The exam is an open book exam. However, usage of laptops and internet access will be prohibited.
Basic thermodynamics (equilibrium thermodynamics), common sense (if available), healthy curiosity (strongly advisable). No advance knowledge in mathematics is needed; however, ability to perform basic logical analysis is absolutely necessary.
