About the project

There is an increasing demand of materials able to be integrated in the new era of devices in the age of the Internet of Things. These have further requirements of reliability and robustness. Ferroelectric materials show switchable by electric field spontaneous surface charge. This switchable charge can be used as a logic state in a capacitor, or to modulate the conductivity of a so-called channel in a field effect transistor architecture device or of the tunneling current in ferroelectric tunnel junctions. As ferroelectricity steams from electronic processes, it is intrinsically robust and reliable, in addition of being energy efficient. The discovery of ferroelectricity in doped hafnium oxide, HfO2, which is a material compatible with CMOS processes, makes this material ideal candidate to be implemented in more efficient memory devices.

ICMAB has the capability to growth such ferroelectric material (HfO2) with state-of-the-art crystalline quality. Thus, the framework of the present project is the development of devices based on highest quality ferroelectric oxide materials. During the project, the postDoc will work on the development of materials involving extensive structural (high resolution x-ray diffraction, synchrotron techniques, etc.). Most importantly, electric characterization (resistance measurements, ferroelectric characterization, etc.) will be the core of the project. Electric characterization dynamics at the nanoscale will be performed using atomic force microscopy. Optical lithography at clean room facilities will be a final necessary step for device fabrication.

The PostDoc will integrate a group (See webpage here: with students and researchers with diverse expertise and aims. The PostDoc will be in charge of mentoring/supervision of PhD students. The project will also be integrated in in-going collaborations with other Spanish and international groups. The work will be supervised by Ignasi Fina and Florencio Sánchez with an intensive production and several on-going projects regarding the topic during the last years
