Metal as floating gate (FG) in combination with high-k interpoly dielectrics (IPD) is seen as a possible solution to continue the scaling of NAND Flash technology node beyond 25nm. We have investigated the thermal stability of TaN metal as FG in combination with Hf based high-k IPD stacks. IPD leakage is found to worsen with high temperature anneal and causing degraded memory behavior. Comparative...
We present the integrated chip-scale tuning of multiple photonic crystal cavities. The optimized implementation allows for large tuning (20K/mW), with deterministic resonance control towards all-optical analogue to electromagnetically-induced-transparency on-chip.
A single-walled carbon-nanotube-array-based (SWCNT) strain sensor was proposed and its fabrication technique was presented, which afforded more simple process than individual SWCNT-based sensor. A novel selective treatment of strain-based electrical breakdown was utilized to leave the SGS-SWCNTs with high gauge factor in the array. The SWCNT-array strain sensor were used for weighing experiment and...
We present experimental analysis of weak coupling for monolayer lead sulfide quantum dots coupled to silicon photonic crystal cavities between 4 K and room temperature, as well as power-saturation measurements of dots at 4 K.
The crystal structures and magnetic properties of (Fe0.6-Co0.4)100-XMx (M=Ti, V, Zr, Nb, Y, Cu, Pt, Al, Si, Ge, X=0 to 10) alloys annealed at 900??C were investigated. The crystal structures were bec for M=V, Nb, Y, Cu and Pt, a mixture of bec and fcc for M=Ge with X=2 to 4, and bec plus unidentified structures for M=Ti and Zr. The saturation magnetic flux density Bs decreases sharply for M=Ti, Nb...
