Integration of Van der Waals heterostructures using 2D Printer

Here, we demonstrate the rapid integration of Van der Waals heterostructure (VDW) on top of a Si photonic chip (IMEC) by precisely placing two different 2D materials  (semiconductor (2H MoTe2) and insulating (hBN)) by using our novel 2D printer technique for on-chip photonic devices.

2D Material Printer

We demonstrate a novel method of transferring 2D materials resembling the functionality known from printing; utilizing a combination of a sharp micro-stamper and viscoelastic polymer, we show precise placement of individual 2D materials resulting in vanishing cross-contamination to the substrate.
