“…PFM is a standard technique used extensively to investigate domain microstructure and dynamics of polarization in classical ferroelectric materials. It exploits the converse piezoelectric effect and detects lattice deformation due to an applied electric field (29,30). To ensure pristine surfaces for the investigation, we prepared freshly cleaved WTe 2 single-crystal samples (several tens of micrometers thick; Fig.…”

“…Nonetheless, if the flow of large electrical currents can be prevented, e.g., by insertion of a dielectric layer between the contacts, then it is possible to apply an electric field to WTe 2 and realize ferroelectric switching. To achieve such a configuration and to preclude the possibility of direct charge injection (30) from the tip into the WTe 2 , we prepared thin film samples in a capacitor geometry (Fig. 3A and see Materials and Methods for details).…”

“…Additional information on the symmetry and ferroelectricity of the film was obtained by piezoresponse force microscopy (PFM) (Ref. 46). The as-grown out-of-plane ferroelectric state is oriented toward the LSMO bottom electrode, evidenced by the solid contrast of the PFM phase image [ Fig.…”

“…De manera general, los microscopios SPM están conformados por tres partes fundamentales: a) la sonda, b) el sistema de barrido y mecanismo de retroalimentación, y, c) los controles electrónicos. Cada una de estas partes contribuye de manera determinante en la resolución espacial que se alcanza, así como en el tipo y magnitud de la interacción que se miden (Sharma, 2016). En este escrito, sería imposible resumir los tipos y logros de todas las técnicas SPM que se manejan actualmente, a tal efecto se mencionarán únicamente las técnicas más relevantes que son la microscopía de efecto túnel (STM) y la de fuerza atómica (AFM) (figura 9), así como sus alcances recientes que han revolucionado la forma de estudiar y cuantificar un gran número de propiedades de superficies e interfaces.…”

En el caso de puntas cuyo ápice corresponde a un átomo individual, se pueden obtener cambios en corriente del orden de pico amperes, y desplazamientos verticales en el rango de los picómetros, mientras que la resolución lateral puede alcanzar valores de 1 Å (Sharma, 2016).…”
