Al2O3/InSb/Si quantum well MOSFETs having an ultra-thin InSb layer
The fabrication and the properties of Al2O3-InSb-Si QW MOSFETs having an ultra thin InSb channel layer is reported. The good characteristic of ID-VD with an transconductance of 67 mS/mm demonstrates that the ultra thin InSb channel layer grown directly on Si can be used for MOSFET channels. The results show that the InSb/Si pseudomorphic quantum well MOSFETs is a promising candidate for future VLSIs.
The photoemission study of InSb/HfO2 stacks upon N2 rapid thermal annealing
Abstract Antimonide based III-V materials are widely used in quantum-well transistors and long wavelength optoelectronic devices benefit from their narrow bandgaps and high carrier mobilities. Interface chemistry has proven to be important in establishing reliable devices. The InSb/HfO2 stacks have been systematically studied upon atomic layer deposition (ALD) and rapid thermal annealing (RTA) at 325 °C and 400 °C, utilizing X-ray photoelectron spectroscopy (Al Kα1) and synchrotron radiation photoemission spectroscopy. No “clean up” effect was observed after the ALD process. The interface oxidization, elemental diffusion and substrate oxide desorption have been observed upon the RTA process. This work highlights the importance of substrate passivation prior to ALD process to obtain a thermally stable InSb/HfO2 interface for InSb based devices.
Immersive haptic interaction with media
New 3D video representations enable new modalities of interaction, such as haptic interaction, with 2D and 3D video for truly immersive media applications. Haptic interaction with video includes haptic structure and haptic motion for new immersive experiences. It is possible to compute haptic structure signals from 3D scene geometry or depth information. This paper introduces the concept of haptic motion, as well as new methods to compute haptic structure and motion signals for 2D video-plus-depth representation. The resulting haptic signals can be rendered using a haptic cursor attached to a 2D or 3D video display.
