High-density (∼ 80/um2) vertical InAs nanowires (NWs) with small diameters (∼ 28 nm) were grown on bare Si (111) substrates by means of two-step metal organic chemical vapor deposition. There are two critical factors in the growth process: (1) a critical nucleation temperature for a specific In molar fraction (approximately 1.69 × 10−5 atm) is the key factor to reduce the size of the nuclei and hence...
Because of different characteristics, the performance of traditional mobile ad hoc networks (MANETs) routing protocols is demonstrated poor in vehicular ad hoc networks (VANETs). Therefore, many routing protocols have been designed for VANETs during past few years. Most of these protocols utilized vehicular traffic to find optimal routing paths in urban environments. Although choosing the road segments...
