Quartz crystal is an important electronic material. When a quartz wafer cut in a certain direction is subjected to mechanical stress, an electric field or charge proportional to the stress will be generated, which is called the positive piezoelectric effect. On the contrary, when the quartz wafer is subjected to an electric field, it will produce a strain proportional to the electric field, which is called the inverse piezoelectric effect. The positive and inverse effects are collectively called the piezoelectric effect. Quartz crystal not only has piezoelectric effect, but also has excellent mechanical, electrical and temperature characteristics. The resonators, oscillators and filters designed and manufactured with it have outstanding advantages in frequency stabilization and frequency selection.


According to different cutting angles, quartz crystals can be divided into different cutting types such as AT-, BT-, CT-, DT-, NT-, GT-, Z-, etc., as shown in the figure below. Different types of quartz crystals have different elastic constants, piezoelectric constants and dielectric constants, which in turn show different oscillation modes and temperature characteristics in the performance of quartz crystal devices.

IntelliSuite software can perform physical-level simulation of different cutting processes such as AT-Cut, BT-Cut, Z-Cut, etc. for quartz crystals, and at the same time, it can simulate the performance of quartz crystal structures or devices with different cutting shapes.
