A G R E AT E R M E AS U R E O F CO N F I D E N C E materials with high carrier mobility, which is what's sparked much of the interest in graphene. This one-atom-thick form of car- bon exhibits the quantum Hall effect and, as a result, relativistic electron current flow. Researchers consider Hall effect measure- ments crucial to the future of the electron- ics industry. Materials with high carrier mobility allow creating devices that obtain maxi- mized current flow at lower power levels with faster switching times and higher bandwidth. Hall Effect Measurements A manipulation of Ohm's Law (Figure 2) shows the importance of carrier mobility in maximizing current. The current is directly Essential for Characterizing proportional to carrier mobility. The options for maximizing current flow through a device include increasing voltage, High Carrier Mobility charge c
