Latest Patents

Ohlsson's latest patents focus on the directionally controlled growth of nanowhiskers. These nanowhiskers are engineered to grow in a non-preferential direction by regulating nucleation conditions, which inhibits growth in a preferential direction. In a preferred implementation, <001> III-V semiconductor nanowhiskers are cultivated on an (001) III-V semiconductor substrate surface. This method effectively inhibits growth in the preferential <111>B direction. For instance, <001> InP nanowires were successfully grown using metal-organic vapor phase epitaxy directly on (001) InP substrates. Characterization through scanning electron microscopy and transmission electron microscopy revealed that the wires possess nearly square cross sections and a perfect zincblende crystalline structure, free of stacking faults.
