Single Crystalline Boron Nanocones: Electric Transport and Field Emission Properties

Single crystalline boron nanocones are obtained by a simple chemical vapor deposition method. Electric conductivity values of boron nanocones are (1.0-7.3) x 10(-5) (Omega cm)(-1). Results of field emission show the low turn-on and threshold electric fields of about 3.5 V mu m(-1) and 5.3 V mu m(-1), respectively. Boron nanocones with good electrical transport and field emission properties are promising candidates for application in flat panel displays and nanoelectronics building blocks.
