We evaluated an independent multi-walled carbon nanotube (MWNT) probe by using tomography with a high-resolution transmission electron microscope to verify the three-dimensional structure of the probe tip. The new method of probe evaluation revealed the following features: (i) cutting the end of the MWNT probe caused the wall structure to disintegrate and(More)
We have successfully demonstrated the strain control of the self assembled Stranski - Krastanov (S-K) InAs quantum dots (QDs) using double-cap procedure. Ga<inf>x</inf>In<inf>1&#x2212;x</inf>As second cap layer was introduced to compensate the strain of InAs QDs, and obtained the Ga composition of Ga<inf>x</inf>In<inf>1&#x2212;x</inf>As second cap layer to(More)
