In 1999, he and Lieber published a highly cited paper on electrostatically controlled carbon nanotube NEMS devices.

[3] In February 2005, his group at Columbia reported electrical measurements of thin graphite films produced by an atomic force microscope technique.

[4] In September 2005, they reported observation of the quantum Hall effect in single graphene layers[5] simultaneously with the group of Andre Geim,[6] and in 2007, the two groups jointly published observations of the quantum Hall effect in graphene at room temperature.

[7] Kim's group authored an influential paper in 2007 describing a transport gap introduced by lithographic patterning of graphene to form nanoribbons.

[11] Kim was awarded the 2008 Ho-Am Prize in Science "for his pioneering work on low-dimensional carbon nanostructures".
