A liquid-ejecting head including a pressure-generating chamber communicating with an nozzle, and a piezoelectric element having a first electrode, a piezoelectric layer arranged above the first electrode, and a second electrode arranged above the piezoelectric layer. An internal electric field in the piezoelectric layer is biased toward the first electrode or the second electrode and no voltage is applied to the first electrode or the second electrode.

摘要:
A liquid ejecting head including a fluid channel forming substrate including a pressure generating chamber communicating with a nozzle opening that ejects a liquid droplet and a piezoelectric element. The piezoelectric element has a first electrode, a piezoelectric material layer that is provided on the first electrode and has a perovskite monoclinic structure, and a second electrode formed on the piezoelectric material layer opposite to the first electrode. An angle formed between a direction of an electric field generated between the first and second electrodes and an orientation of a polarization moment of the piezoelectric material layer is greater than an angle formed between the direction of the electric field at a time when the piezoelectric constant of the piezoelectric material layer reaches a maximum level and the orientation of the polarization moment.
摘要:
A droplet-ejecting head including a substrate including a pressure chamber communicating with a nozzle hole and also a piezoelectric element that includes a lower electrode, a piezoelectric layer which is formed above the lower electrode, and an upper electrode formed above the piezoelectric element and that causes a change in pressure in a liquid contained in the pressure chamber. The piezoelectric layer includes a first piezoelectric sub-layer located on the lower electrode and a second piezoelectric sub-layer located between the first piezoelectric sub-layer and the upper electrode. The first piezoelectric sub-layer has a polarization axis predominantly directed in an in-plane direction of the first piezoelectric sub-layer. The second piezoelectric sub-layer is predominantly (100)-oriented in the pseudocubic coordinate system.
