Hypofractionated Radiotherapy Induces ISG15+MHC‐I+ Neutrophils to Augment Anti‐Tumor Immunity and Prime Immune Checkpoint Blockade Responses in Rectal Cancer

Advanced Science, EarlyView.
ABSTRACT Our previous clinical trials had demonstrated that neoadjuvant hypofractionated radiotherapy (HFRT) combined with immunotherapy yields promising clinical outcomes in locally advanced rectal cancer (LARC). However, this combined modality benefits only a subset of patients, highlighting the need to uncover the mechanisms underlying how ...

Ion implantation in 4H–SiC

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2008
Abstract Silicon carbide offers unique applications as a wide bandgap semiconductor. This paper reviews various aspects of ion implantation in 4H–SiC studied with a view to optimise ion implantation in silicon carbide. Al, P and Si ions with keV energies were used.

Layered Epitaxial Growth of 3C/4H Silicon Carbide Confined by Surface Micro-Nano Steps

Crystals, 2023
In this study, we used a horizontal hot-wall CVD epitaxy apparatus to grow epitaxial layers on 4° off-axis 4H-SiC substrates. Epitaxial films were grown by adjusting the flow rate of the source gas at different levels.

Anti-reflective nano- and micro-structures on 4H-SiC for photodiodes [PDF]

, 2011
In this study, nano-scale honeycomb-shaped structures with anti-reflection properties were successfully formed on SiC. The surface of 4H-SiC wafer after a conventional photolithography process was etched by inductively coupled plasma. We demonstrate that

Ultraviolet Photodetectors Based on 4H‐SiC With Honeycomb‐Like Light‐Trapping Structures

Advanced Science, EarlyView.
A facile photoelectrochemical etching method creates honeycomb‐like light‐trapping microstructures on SiC. These microstructures suppress UV reflection and enhance absorption by extending the optical path and facilitating multiple internal reflections, while strengthening the local electric field.
