Quasi ballistic transport in a 2 dimension electron gas was explored and tunneling through an electrostatic barrier induced by metallic gates on the top of the heterostructure was demonstrated. For energies above 36 meV we observed the LO phonon emission, leading to a short mean free path. At energies below the phonon energy we find a mean free path of the order of 2 µm, about an order of magnitude longer than expected theoretically for electron interactions. The angular distribution of hot electrons injected from a point source was shown to be collimated and could be steered by controling the electrostatic profile of the injector. In addition we demonstrated operation of electrostatic lens which opens a new branch in semiconductor physics, namely, electron-optics in solids.
