A New Semiconductor-Wafer Market Based on the Deepening of Surface Undulations to Form Strongly Textured Atomic Ridges (STAR) With Pitches from 0.6 to 5.4 nm: Model Demonstrations in Electronics and the Physical and Life Sciences

Kendall D.L., Kendall M., Kendall D.L., Kendall M., StarMega Corp, US

A broad patent position has been established that produces semiconductor wafers containing physically-deepened grooves, ridges and quantum-dots on particular crystal planes with perfectly spaced pitches of 0.9 to 5.4 nm determined by the inherent crystal [...]

Single Wall Carbon Nanotube-Based Structural Health Monitoring Sensing Materials

Watkins A.N., Ingram J.L., Jordan J.D., Wincheski R.A., Smits J.M., Williams P.A., NASA Langley Research Center, US

Single-wall carbon nanotube (SWCNT)-based materials represent the future aerospace vehicle construction material of choice based primarily on predicted strength-to-weight advantages and inherent multifunctionality. As such, it is prudent to pursue the development of SWCNT-based sensing [...]
