Micropatterning of single crystals for technological applications is a complex, multistep process.

A novel method for measuring tunneling forces with a scanning tunneling microscope is described.

The frequency modulation due to injection current modulation of vapor-phase-transported distributed-feedback (VPT-DFP) semiconductor lasers is measured as a function of modulation frequency from 1

We have made direct imaging observations of the luminous star forming region W51 IRS 2 with the 10 by 64 pixel Berkeley direct readout infrared camera.

Based on multimode interference imaging, couplers employing a wide multimode waveguiding region are commonly used to divide and combine light in photonic integrated circuits.

Pure screw dislocations are found to be the origin of excess reverse bias leakage in GaN films grown by molecular beam epitaxy on GaN templates.

We have probed the angular momentum orientation of N sub 2 scattered from cold Ag(111) when the N sub 2 approaches the surface along the surface normal.

We have measured the rotational state distribution and the angular momentum alignment and orientation of N sub 2 scattered from Ag(111) at 540 K.

The orientation of the angular momentum of N sub 2 scattered from clean Ag(111) is determined by resonance-enhanced multiphoton ionization.

We demonstrate a great simplification in the long-standing problem of measuring optical frequencies in terms of the cesium primary standard.
