A Better Nanochannel Tungsten Film in Releasing Helium Atoms

Discovering highly radiation resistant plasma facing materials (PFM) is an urgent target for nuclear fusion reactor. In our previous work, a new PFM (nanochannel tungsten film) that consists of many tungsten crystal columns was found having excellent radiation tolerant properties. … Continue reading

Manipulating The Triboelectric Surface Charge Density of Polymers By Low-energy Helium Ion Irradiation/implantation

Triboelectric materials and their modification methods are the cornerstones for fabricating triboelectric nanogenerators (TENGs). Numerous modification methods have been proposed for TENGs, while a highly effective and long-term stable method is still under exploration. Here, a surface modification method using … Continue reading

Substrate Noise Isolation Improvement By Helium-3 Ion Irradiation Technique in a Triple-well CMOS Process

Helium-3 ion irradiation technique is proposed to improve silicon substrate noise isolation by creating a local semi-insulated region with a resistivity over 1kΩ-cm in low-resistive silicon substrate. Noise isolation is improved about 10dB at 2GHz after helium-3 ion irradiation in … Continue reading
