For more than thirty years Philips Research has been engaged in direct bonding. A survey is given of how what was first the study of an optical technology gradually changed into the development of special applications in semiconductor technology. Coo

Fluctuations in the Hall and Shubnikov-de Haas voltages were studied on a CaAs/AlxGa1-xAs heterostructure operating in the integral quantized Hall regime. In the spectral noise intensities two contributions could be distinguished, i.e., a frequency a

We have investigated the spectral noise intensity of the Hall voltage and the Shubnikov-de Haas voltage of a GaAs/Al x Ga 1−x As (x = 0.34) heterostructure operating under quantum Hall conditions. In the spectra three contributions could be disting

We studied the dependence on supercurrent density of the enhancement by microwaves of the order parameter in superconducting aluminum films. Experiments were made on a superconducting circuit that includes an aluminum strip and the input coil of a su

An expression is derived for the Josephson current between two weakly coupled superconductors of which one or both have pairs in a spin-triplet state. It is shown that there can be no Josephson effect up to second order in the transition matrix eleme

We have measured the spectral noise intensities of Hall and Shubnikov-de Haas voltages as well as of the voltage across a GaAs/AlGaAs heterostructure. The frequency dependent part of the observed noise is associated with carrier density fluctuations.

In contrast to previously reported results the critical current in superconducting Al strips under microwave irradiation is shown to reach a maximum value before decreasing continuously to zero with increasing microwave power. The influence of local

Experimentally is found that at constant temperatures the order-parameter relaxation time, τΔ, decreases with increasing power of the microwaves, coupled into a superconducting strip. If the same increase in critical current, that corresponds with

Measurements of emission rates and majority carrier capture cross-sections of Au, Pt, Pd and Rh centres in silicon are reported, and the activation energies associated with the different levels of these centres are determined. Where appropriate, our
