Abstract: We develop an ultra-thin, highly filled, neutron-shielding material. This material exhibits a desirable neutron-shielding performance, and also has certain advantageous mechanical properties and uses. We study the physical properties of shielding materials with different polyolefins as base materials, and investigate the neutron-shielding performance of boron-containing and lithium-containing shielding materials. We furthermore report on the effect of additive amounts of functional additives on shielding properties and physical-chemical properties. We additionally study the effect of radiation crosslinking technology on shielding material properties. We show that, using ethylene-octene copolymer (POE) modified low-density polyethylene (PE-LD), the additive amounts of boron carbide (B₄C) and nano-montmorillonite (OMMT) are 60–70% and 4%, respectively. The optimal radiation dose is 160 kGy, and the shielding materials exhibit good neutron-shielding performance and mechanical strength.

Abstract: This paper reports the successful substrate transfer based on standard IC processing to an alternative substrate e.g. plastic. The device on ultra-thin Si substrate using grinding backside Si and thermo-compression bonding process is proposed. Acceptable electrical performances are achieved means that the substrate transfer process is controlled well. The DC characteristics of nMOSFETs as a function of orientations and device sizes under mechanical strain are also reported. Good performance and reliability of nMOSFETs under mechanical strain is obtained. The results suggest the feasibility of substrate transfer in achieving well-performance nMOSFETs for 3D integration or SiP technologies.

Abstract: A pure AlPO4-11 (AEL) zeolite crystal is optically transparent in visible region and a good insulator with thermal stability up to 1173 K. These excellent physical properties, plus their unique elliptical pore structures, make them an excellent template to fabricate ultra-thin single-walled carbon nanotubes (SWNTs).We studied the polarization dependence Raman spectra for (2,2) SWNTs formed inside the channels of AEL crystals. These (2,2) SWNTs acts as a dipolar antenna, polarized along the crystal channels axis. The polarization angle dependence of the Raman intensity indicates that the enclosed (2,2) SWNTs are highly oriented in the channels with their dipole transition moment mostly along the channels.
