Preparation and Properties of 2D Materials

Abstract

Since the great success of graphene, atomically thin layered nanomaterials—called two-dimensional (2D) materials—have attracted tremendous attention due to their extraordinary physical properties [...]

Controllable modulation of the oxygen vacancy-induced adjustment of memristive behavior for direct differential operation with transistor-free memristor

“…It has been reported that the synaptic plasticity is a basic characteristic of memristors for neuromorphic computing. [35][36][37][38] In this work, since the OVs-LN-OVs memristor has the memristive behavior at negative bias, negative set voltage pulses (V set = −21 V) were applied to TE, and the conductance was recorded by the reading voltage (V read = −2 V), as presented in Fig. S5(a).…”

Machine Learning Assisted Enhancement in a Two-Dimensional Material’s Sensing Performance

“…At the forefront of materials research are 2D materials. 2D materials are materials with a thickness of one or a few atoms that have remarkable qualities because of their distinct structural features at the nanoscale . High-quality 2D materials have been made possible by a contamination-free, one-step, universal Au-assisted mechanical exfoliation process that dates back to the initial separation of graphene .…”

“…2D materials are materials with a thickness of one or a few atoms that have remarkable qualities because of their distinct structural features at the nanoscale. 6 High-quality 2D materials have been made possible by a contamination-free, one-step, universal Au-assisted mechanical exfoliation process that dates back to the initial separation of graphene. 7 This method uses sticky tape to gently remove layers from a bulk substance in preparation for small-sized, randomly shaped materials.…”
