Abstract: A method for use in manufacturing an electronic component comprises forming a layered structure comprising a dielectric structure layer, a channel layer and a gate layer. The dielectric structure layer comprises a first portion and a second portion that differ from one another in respect of fixed charges. The channel layer comprises a two-dimensional material. The gate layer comprises a gate formed above both, the first portion of the dielectric structure layer and the second portion of the dielectric structure layer. A device for use as an electronic component comprises a dielectric structure and a gate above the dielectric structure and a two-dimensional material between the dielectric structure and the gate. The dielectric structure is configured to expose the two-dimensional material to an inhomogeneous electric field.

Abstract: An approach is provided for processing drawing inputs on a mapping user interface to select one or more map elements. An interaction platform receives a drawing input via the mapping user interface. Next, the interaction platform processes the drawing input to determine one or more selection parameters of at least one spatial query. Thereafter, the interaction platform queries at least one spatial index based, at least in part, on the one or more selection parameters, the at least one spatial query, or a combination thereof to determine one or more map elements. Subsequently, the interaction platform causes, at least in part, a selection of the one or more map elements based, at least in part, on the drawing input.
