Single Crystalline Boron Nanocones: Electric Transport and Field Emission Properties

Abstract

Single crystalline boron nanocones are obtained by a simple chemical vapor deposition method. Electric conductivity values of boron nanocones are (1.0–7.3) × 10–5 (Ω cm)–1. Results of field emission show the low turn-on and threshold electric fields of about 3.5 V μm–1 and 5.3 V μm–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.
