In this thesis we will focus on a particular variant of few-layer graphene -- ABA-stacked trilayer graphene. Bernal (ABA) stacked trilayer graphene (TLG) is a multiband system consisting of a pair of Dirac-like massless linear bands and a pair of massive quadratic bands. We have studied the electronic properties of this system in detail and unfolded many interesting physics problems. The whole thesis is structured in the following way. In chapter 2 and chapter 3 we discuss the theoretical ingredients we will need to understand the experimental data presented in this thesis. Chapter 2 focuses on the band structure of graphene and few-layer graphene. In chapter 3 we focus on quantum Hall effect of graphene and few-layer graphene. In chapter 4 we discuss the device fabrication and characterization. Chapter 5, Chapter 6 and Chapter 7 present the original works which are published as papers.
