We investigated amorphous indium gallium zinc oxide (a-IGZO) thin film transistors (TFTs) using different high-k gate dielectric materials such as silicon nitride (Si 3 N 4) and aluminum oxide (Al 2 O 3) at low temperature process (<300°C) and compared them with low temperature silicon dioxide (SiO 2).The IGZO device with high-k …
Thus, from a hypothetical starting point, we experience a much greater contraction by the time we reach gallium compared to aluminium. Note that it is irrelevant that the 3d electrons are there and 'shielding'. Shielding doesn't play that great a role as is often said. Another 'step' can be experienced when going from indium to thallium.
