Heterogeneous integration of single-crystalline complex-oxide membranes

A universal mechanical exfoliation method of creating freestanding membranes of complex-oxide materials with different crystal structures and orientations and stacking them to produce a range of artificial heterostructures with hybridized physical properties is described.

Modularity-based mathematical modeling of ligand inter-nanocluster connectivity for unraveling reversible stem cell regulation

The extracellular matrix is remodeled to form complex interconnected network structures that regulate stem cell behaviors. Here, the authors modulate extracellular matrix-like networks using magnetic nano-blockers, adjusting stem cell behavior by changing ligand inter-cluster connectivity. This dynamic system provides new insights into cell-material interactions for tissue regeneration.

Vertical full-colour micro-LEDs via 2D materials-based layer transfer

We report full-colour, vertically stacked µLEDs that achieve exceptionally high array density (5,100 pixels per inch) and small size (4 µm) via a 2D material-based layer transfer technique, allowing the creation of full-colour µLED displays for augmented and virtual reality.

Heterogeneous integration of high-k complex-oxide gate dielectrics on wide band-gap high-electron-mobility transistors

Hyun Kum and colleagues report on the heterogeneous integration of high-k single-crystalline strontium titanium oxide within gallium nitride high-electron-mobility transistors. As the dielectric material is epitaxially grown and transferred, they achieve low defect density between the gate oxide and transistor heterostructures.

High-throughput manufacturing of epitaxial membranes from a single wafer by 2D materials-based layer transfer process

Multiple alternating layers of two-dimensional materials and epilayers are grown on III–N and III–V substrates in a single growth run. Then, each epilayer is harvested by mechanical exfoliation, producing multiple freestanding membranes from a single wafer.

In situ self-assembly for cancer therapy and imaging

In situ self-assembly is advantageous for cancer therapy and imaging because of the efficient deep-tumour targeting, enhanced blood circulation and negligible drug resistance of the resulting nanomedicines. This Review discusses extracellular and intracellular in situ self-assembly based on endogenous and exogenous stimuli for cancer therapy and imaging applications.
